Thanks for all the advice guys...i tried bringing in files i already use in lr2 and it seems fine, but it does give me some anxiety...so, I think I'll duplicate files to work on for the lr3 beta and not care if 'something' goes wrong...
also tried the virtual copy and converting to process 2...like you said Francois, some images i'm seeing no change, others slightly more...it isn't huge, well, not on the files i tried anyway...
thanks...
