I have gone through the forums and know about the registry hack to make C1 "work" with in Windows 7. If you call constant crashing "working" then sign me up for something better. I also have Win XP mode setup with C1, but many times it becomes unresponsive when trying to edit objects. I can filter through the tree and contexts just fine. It is set up the same exact way I had it on my XP OS.

Windows 7/XP mode - 2
Me - 0

I have seen people state that there is a compatible version of C1 that is on the GW8 SP1 CD. Can someone let me know what version this is? I am currently running 1.3.6h
