And so far as I can see, it's the only one. Checking the box the check mark does not appear. The tool actually works, I just can't see it as I move the sliders. I recently installed an update for the video card, but rolling back the drivers made no difference

Which version of Photoshop are you using?

Sorry! Photoshop CC 2014.2.2Release.

I find absolutely no info on this problem. I recently updated the video driver, and the garbage that came with it did mess up some programs, but seemingly not PS. I uninstalled it, then updated the driver only. When this showed up, I rolled it back, but no dice, so now it's the current AMD driver sans gaming stuff. Radeon R7 200 series video

I tried 4 machines here at work - can't reproduce.

Well then I expect that it's a corrupt file since it only affects Shadows/Highlights. A uninstall/reinstall? If so, I've been reading on the preferred method, which seems to include a cleanup utility, although that was suggested for more serious problems. Can I simply re-install over the top?

The older video card shows the same problem.

Photoshop hated that card!

Reinstalling might help - but I really don't know the cause, and suspect that the video driver might still be involved.

I took it all the way back to the driver that worked up till now, 13.251.0.0. The entire suite also loaded as the rollback in Win 7 would not go that far back.

It's running different now. The check mark is present, but it won't easily turn off. What really controls it is Ctrl Z and it isn't what you might expect. I can see the parameters change and watch the image change, but the parameter change is now unstable, that is when it returns to the default, it isn't actually default. Only Cancel returns to the starting point. Continual clicking Ctrl-Z is not back and forth, it jumps around.

That most likely means that there's a system error happening during the redraw that is messing up the commit status of the new values. Which still means a video driver bug. I'm just not sure how it can be so specific to that one dialog...

It's the only error I found. All other Preview check boxes work. The tool runs anyway. I have another video card to try and I'll do that tomorrow.

Thanks Chris

Looks like I have more. This happened when I had an original and copy open on the desktop at the same time. Really suggests video. Did not swap card yet. Newest driver.

Newest driver from the GPU vendor?
And yes, that looks like a driver bug.

Well, I downloaded a driver uninstall and clean up, then installed the closest driver I could find to what I had running for the last 2 years, recalibrated the screen (ugh! all the color settings choices I had, including the Dell default and my last two results with the i1 disappeared!) It running, calibrated and profiled to a tight tolerance (0.41) Still no relief with that tool. I haven't tried to see if the red bars show up again; the last time I tried before all this reinsallation of drivers it was showing up.

No change. Two video cards, clean re-install, no change. Seems to me the next step is to re-install Photoshop, or maybe install Lightroom and see if it shows up there.

I have been running Photoshop this morning and seemingly, the only remaining problem is the S/H tool Preview. I say seemingly, because those red bars have not shown up, either because the problem no longer exists due to the deep video driver rollback or maybe I haven't hit the right command to trigger it.

The various instructions for uninstall and re-install gives me pause to do just that due to differing suggestions (Use the clean tool, don't use it, etc.). If re-install is advisable, do I need to use the clean tool? If I do, what will I lose in my overall settings?

Thanks

Reinstalling Photoshop is not likely to change this. But when you uninstall Photoshop, you have a choice of whether you want to remove the preferences or not (if you don't, then you won't lose anything).

Reinstalling the drivers shouldn't change much.

I don't know what is going on here, but I posted a big reply, I saw it posted when I clicked Reply, and now it is gone. And this isn't the first time! So I am forced to do it in Open Office and save it just in case.

What I posted is that I have a full size backup for C drive, one at 03-04-2015. So I created another one for today, then rolled back to that date.

The problem with Edit>S/H does not exist in the 03-04 backup. I did no check for the second problem here, the red bars. Because I need to access files important since 03-09, I again used Restore to get back to today's version. Now, not only does S/H Preview not work, nothing works in the Shadow/Highlight tool. The video driver in the 03-04 backup is newer than the one I installed yesterday, but runs with no difficulty.

My conclusion is that it isn't a hardware problem. It also occurred to me that the secret lies in the difference between Backups 03-09 and 04-29, and that a careful comparison could yield positive results. Therefore, I'll do what ever I can to assist, supplying those backup files as necessary. I use Macrium as the software backup utility so the file is in their format.

Two major changes I did between then and now; one was a way to update the drivers for the Epson 3200 scanner to run on a 64 bit OS and the other was, of course, the updates from Adobe since then including all current ones to 04-28.

Let me know what you want to do and in the meantime, I 'll use the 03-09 Backup Restore an bring it up to date as the current C drive contents.

Hopes this runs this time!

Let us know what you find. Yes, driver bugs can be aggravating to diagnose...

All I can do is to roll back, then at each change, run a check. Other than that even though I have a Hex Editor and Process Explorer available, I'm a babe in the woods as to interpreting!

I could load the files in HxD but they are many GB deep!

It's running correctly now.

I decided the best course of action was to use the backup from 03-09. As soon as it loaded, I ran a Malware check and that found 2 entries. Cleared them and proceeded carefully , taking notes.

Photoshop ran fine, actually rather fast compared to the afflicted version. I did some cleanup, then started updating -Windows Updates etc setting Restore points as I went.. Everything ran so well that I generated a new full backup of C drive.

Bottom line: All is well, is fast and I haven't a real clue! The only thing I did not re-install is a free Kapersky Malware I installed when it was reported by them of a peculiar hack. I didn't have it but I didn't uninstall Kapersky. Since this is the big difference so far as it goes, I have to be suspicious. Years ago, I could not run old Photoshop 6 because of Norton (remember those days?)

Besides clearing the Photoshop problems, the machine is significantly faster, a problem I was going to look into once the PS problem was fixed. I suspected even then they were related.

Sometimes, many times, the only solution is what I did, which solves a problem yes, but doesn't answer any questions. I chafe against such solutions.

Fingers crossed, and thanks again Chris!

Addendum:

Looks to be systemic. I have had a continual playing problem with MS Media Player, which preceded this problem significantly, so I didn't tie them together, but the player re-initialized and played flawlessly.
