Thanks for all the suggestions. Yes, my system is up to the challenge of LR, generally speaking. I have 32GB of RAM, an AMD FX-9590 CPU, an AMD Radeon R9 280X-DC2 video card, a 500GB C; drive (primarily the Win 10 OS), and a 1TB drive for my various programs and half a dozen external drives I use at different time, all powered by a 1000w PSU. So, I think the basics are pretty much covered. But, LR is definitely crashing my system. No other programs locks me up. Only when using LR do I experience system freeze. Three times today, an counting.
Today an added burden. Every time I run LR, I've noticed it's using about about 13% of CPU time just sitting there (I'm not doing anything). I have the GPU unchecked because I found performance far worse with it selected. Sad. LR use to be fleet of foot and fairly compacted. Now it's bloated and slow. If I didn't rely upon it for certain cataloging aspects, I might use something like Photo Ninja (which i tried as was impressed by). I hate the rendering by Capture One (have used it since the earliest days). I just don't care for it's controls and color. DxO is much improved, and for certain files, it's great -- at times better than LR. Quite frustrating dealing with these freezes. One of the times today, I almost had to do a system recovery, thanks to LR.
