Lightroom: After an unsuccessful drag of an image, dragging is no longer possible

In the Lightroom Library, when dragging an image within a folder to rearrange its position, if I accidentally drag it to a spot that isn't allowed (like to another folder), I get an error message telling me the correct way to move images between folders. Fine. However, after that messages appears, I can no longer drag any images--the drag functionality is dead. When I try grabbing an image with the mouse to move it, nothing happens. The only solution for this is to exit and restart Lightroom. If I do this, I can drag again. 

I have seen posts instructing people on where to grab an image to drag it--I understand that I need to grab the actual image rather than its frame. That is not the problem. This is clearly a bug.

I am using Adobe Photoshop Lightroom CC 2015.10 on Windows 10 Pro 64-bit v.1703, OS build 15063.296, on an Intel i7 machine with 16G memory.

  • frustrated--I haven't seen any posts acknowledging this is a bug.

"if I accidentally drag it to a spot that isn't allowed (like to another folder), I get an error message telling me the correct way to move images between folders."

Is this the message you're referring to?

Or did it say something else?

No, I think it was just informational (i.e., no action button). I wish I'd captured it. It said something like "If you want to add/move you have to do xxx". It always happened when trying to move an image to the left of another image that is at the left end of a row.

Since I already knew that I had accidentally dropped the image in the wrong spot, I just quickly dismissed the message without reading it thoroughly, and tried to move on. But dragging was dead at that point.

I'll try to deliberately recreate it and grab a screen shot.

Getting a screenshot of the error message would be very helpful, because that would suggest exactly where you dropped the image.  When I drag an image to a folder, I get the message above, and hitting Cancel doesn't affect future drags.

There's an open bug involving dragging of folders with similar symptoms, but that one can be easily reproduced.  Until there's a recipe for reproducing your issue, Adobe is very unlikely to pay any attention.

I was able to recreate the problem and get a screenshot (see above). I had selected 2 photos and was trying to drag them from about position 100 to about position 20 in the Grid view in the Library. When I dropped them, I got this message. And this time I wasn't trying to drop at the very left side of the grid--it was more towards the middle, so that doesn't seem to be part of the problem.

I don't understand the message in the context of what I was doing--I hadn't picked up a folder or anything else--just photos in the grid. It's possible that during the drag, the mouse moved over the folder area, but I didn't let go over the folders. But that wouldn't explain the message anyway--I definitely picked up photos from the grid.

I have tried to deliberately recreate the error condition, but haven't been able to do so yet. So either it's an intermittent problem (which I know developers love), or I did something additional that was so minor it didn't register, which is why I can't recreate it.

Anyway, once I dismissed this message, I was no longer able to drag any photos until I quit and restarted the program. I've now had this happen at least 5 times during the past couple of weeks. I can't say for sure that it is an issue from an update though, because I hadn't been using the program heavily until recently--I was learning, and only recently started doing actual work.

 I hope this helps! I will keep trying to recreate the issue to see if I can determine any other triggers.

I discovered one way to produce that error message: Try to drag a pic from the filmstrip to grid view or vice versa. However, when I do that in 2015.10.1 on either OS X or Windows 10, dragging continues to work after dismissing the error.  

Try dragging from the filmstrip to grid view and vice versa.  Does dragging always stop after dismissing the error, or just sometimes?

Yes that does create the message and dragging still works after dismissing it. However now that I know what legitimately triggers it, I will try to notice what causes the buggy behavior. Thank you!

I'm now having a second drag and drop issue. I don't know if it's related, but here's what happens:

I begin by dragging individual photos, one by one, further up in the order on the grid. I'm doing this because when I scanned the photos, they were scanned in reverse order so I need to reorder them. 

To do this, I select an image upwards on the grid to mark my insertion point. I then drag photos from below in the grid, and drop them in front of the selected photo. This works fine for a while, but after a number of drags and drops, the selected photo "freezes."

What I mean by this is, I am no longer able to drop photos in front of the selected photo--when I let go of the dragged photo, it actually lands behind the selected photo, even though I dropped it in front. At first I didn't realize this was happening and it really messed up the order of my photos!

Now that I see it happening, I can fix it: I drag the selected photo, and drop it behind the photos I recently moved up (that landed in the wrong spot). After I do that, everything is fixed, at least for a while. Then it randomly happens again.

It's clear to me there are some bugs in the drag and drop functionality of the Grid view. Perhaps this is not a typical use case for Lightroom. I'm a photo organizer, not a photographer. I take my clients' photos and organize them and add metadata. The order matters because often clients have a legend, at least for trip photos, that identify each image. I need them in the right order so they can be tagged correctly.

Many of my clients' photos are paper and must be scanned. And since the scanning process often gets them out of order, I have to reorder them manually--hence all the dragging and dropping.

Unfortunately there isn't anything I can screen grab of here, but hopefully I have captured the steps that cause the bug. Please let me know if I should move this to a new thread.

Merging with another bug report.

Please reference the new conversation here: Custom order in folders fail

See this topic for a possibly related bug: https://feedback.photoshop.com/photoshop_family/topics/re-arranging-photos-in-collection-stops-funct... The symptoms sound similar, but the other topic concerns collections, not folders, so I'm not merging the two topics.
