You are listing a single bug in 6.35 that only affects someone using the switchbar (not someone using the treebar) and *only* if the mouse is left sitting over it. If you move the mouse off the switchbar, there is no longer a problem. That's not a very significant problem that would prevent 6.35 from being used on Windows 7. I actually use the switchbar in 6.35 on one client and never have a problem because I don't let the mouse sit over the switchbar. So, yes, there are bugs (there will be in 7.x as well as all other versions), but they do not make 6.35 unusable in Windows 7.
I also doubt you'll see a separate build.
