Lightroom: Spot Removal freeze (Win 7)
I have just bought Light Room3 (v3.5) on Dell Latitude E6520 with an Intel Core i7-2720QM processor, 8GB RAM and a 256GB SSD. I store my photos on a RAID5 NAS. When using the spot removal on .jpg files (so far it has not happened on raw - Nikon D7000 16MP .nef files) if use the tool more than twice in a row, LR freezes - the little hand makes a fist, processor works, memory used increases - looks like program is in a never ending loop). If I stop the program and re-start, the change is there. I notice on the web that this has been a problem for over a year but I cannot find a sensible fix. (There are many suggestions about bad drivers, bad power supplies etc.) Is there a fix? if so, what is it and where do I get it?

Doesn't happen on LR2, but I'm not sure about earlier LR3 versions as I haven't had time to go back and test.

I'd go directly to the nVidia or AMD/ATI site to make sure you have the latest drivers.

IMHO, there is definitely a problem in LR 3.5 cloning in 1:1 zoom level related to JPEG images and multicore processors.
I also did some testing related to the thread Jim mentions at lightroomforums.net. I tested with both my
and they both show the hangs (freezes) in spot removal when done in a 1:1 zoom level. Dedicating LR to run on one core only makes the problem disappear on both systems.
Please see also this thread over at the U2U forum which discusses the same subject.
This is a sample image on which the problem occurs quite heavily. I don't know what kind of JPEGs show the problem the most, I've noticed that pixel dimensions have an influence (very small JPEGs seem not to show the problem).

P.S: If you need any instructions on how to reproduce the problem, please ask. The original post in the thread Jim mentions describes it pretty well though.
I've also tried to record a screen capture of the behaviour, but while running my screen capture software, the problem does not occur :-(

I did the same using a jpg version of the same photo (from the camera) and always had problems at 4:1 zoom when LR3 'froze after the 1st or 2nd attempt.I had no problems at 1:1 or 11:1
I repeated using a LR3 export of the same photo (1024 * 678pixels) and had some problems at 11:1 zoom. This happened less often than in the previous test. I had no problems at 1:1 or 4:1

I noticed when LR froze, one core was always working harder that the others. If I unselected that core, 9 out of 10 times LR 'unfroze' as I pressed the OK button in the 'Processor Affinity' pane.

No, I'm afraid it still happens but it seems sometimes to be more likely to come back by itself - after 20-25 seconds. (at least it did it twice which I'd not seen before)

I haven't installed 3.6 yet, I'll test and report back after the week end.

First test: made two clone spot removal attempts (each case rather extreme long distance clones), got the closed-fist lockup on the second one and this did not clear so had to force quit using Task Manager.
Second Test went better, was able to apply copious spot removals but did not attempt to update the sampling spot from the LR selection. After 20-30 of these I then started adjusting the sampling area and got the 'temporary for a few seconds' closed fist. Slow and jerky, but could survive.
Third Test, repeated the second test, but this time after successfully applying spot removals using default sampling area, then got the full closed fist lockup when attempting long distance clones which did not recover. Force quit required.
Fourth Test: tried to repeat the first test, and on the very first attempt the cursor/fist simply disappeared (the cursor reappears when I move outside the Lightroom window).and still hasn't reappeared within Lightroom while I was typing this note. Another force quit required.
So basically no change at all from 3.5.
Question: was there a specific fix applied in 3.6 for this bug?
