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?
