Sounds like a provocative title but it does describe the problem.
I find that when I'm scanning through my images after import in order to rate them (in my case I use # of stars) after a couple of hundred images LR begins to dramatically slow down.
Specifically, it takes longer and longer for the image to come into focus. After awhile it may take three or four seconds and then, if I continue working, I begin to get an "unknown error" notice.
At this time I must close out of LR and then reload in order to continue.
I'm working on a PC with Dual Core, XP Pro, and 4 gigs of memory.
Is this a common problem or am I just lucky? Any thoughts as to what to do to correct it?
Thanks.
