Decided not to reinstall at this point. HOWEVER - I accidentally stumbled on something yesterday. I don't store any photos in PSE, BUT I found a whole bunch of stuff stored in there! I just got a new camera, and am deciding how I want to handle my photos this time around, and discovered folders full of things I've edited along the way. I mean, TONS of stuff! So I deleted the whole mess (yes, these items are stored elsewhere, no worries!). So maybe that will help, I dunno. I haven't had time to really get serious doing something, but did a tiny bit of editing to see if it would freeze up on me. It didn't - but need to put it to a better test. Maybe I will find time today for that. I will let you know.
Would be nice if that's the problem, wouldn't it?
