I've been using it most of yesterday in 64-bit Windows Vista and it works like a charm (thanks again, Daeley, for the fantastic new features- I did several "mirror image" puzzle pieces, and it made them a snap!). My heart goes out to you, Joe- the day or so it took to sort out the problems I was having seemed like a lifetime. I bet you'll get it working, though- you Linux folks start out about ten times brighter than the rest of us. I tried seriously hard to go to a Linux-based office environment about five years ago- used a consultant, the whole nine yards. It just didn't happen.
Good luck!
