XP went 64bit and it was horrible.
0 driver support and many programs not working.
It was quite a nightmare.
So Lee-m, I'll summarize that if I had another viable option, I'd take it.
Right now is either RTG fixes the bug, or I need to replace PC to overcome it which is not an option currently. Most certainly not due to a programming bug.
Personally I don't think anyone should replace/reinstall their OS, just to overcome a bug in a program., which for some people is even more difficult than replacing the PC entirely.
