happends to me from time to time. (less than once a week). I restart LR and everything is O.K.. I do not know why this happens.
For some of us, yes; for others: no.
Some influential factors:
* Lotsa develop presets.
* Lotsa plugin menu items.
Adobe is probably still investigating a fix for this, so any correlative info you could provide would probably be appreciated. e.g. under what conditions it happens, under what conditions it does not...
Hey Guy's, Thank you for the recommendations to fix his problem and I did restart my browser, etc.. and all was corrected. But, I have been with Lightroom for a while, starting with LR3. I can not remember having one problem, except for my errors, until I started with LR5 and I have some kind of problem hourly! I do not have many presets or plug-ins so I don't think that was really a problem. It crashes constantly, I can edit 4-6 photos and then it starts slowing down and I have to do a restart. It does, on occasion, jump around from the develop controls and even changes modes, crashes and sometimes I just wait it out and it will open in the print mode or slideshow! I find photos all over my computer that it sent on its own. I did download and check for malware and other viruses and none were found so I am still troubleshooting everything from my fairly new computer and everything else but I always think when they come out with a newer version to download, it will correct my problems but they only get worse.
