I've been getting this problem while I'm working in Bryce, where all of the sudden, I'm unable to make small increments of object repositioning with my mouse. I grab on to... ANYTHING in the scene (single objects, grouped objects, etc.) and have to move my mouse a few inches of screen distance, before the objects suddenly jump to some invisible "snap-to" distance that's always much farther that I want it to go. I tried saving the file and re-starting Bryce. After re-opening the file, SOMTIMES this behavior stops. Somtimes not. Anyone know what's up and how to fix it?? Thanks a bunch, Norb
