Problem with Physics Constraints and Windows 10!?!?!

If your currently testing win10-64bit like me. Try creating a set of physics constraints, like a ragdoll or something. My ragdoll was working fine with windows 7. But now after the upgrade to…“the big 10!!!” As soon as i create the constraints with python the entire blender-2.73 program closes out in an instant. So I can’t even get debug output…So if you got windows 10, try it and lemme know…

what build of blender? they just patched something about that,

blender-2.73 on Windows 10 home edition 64-bit. And I swear it works on the Windows 7 equivalent.

I just downloaded the latest version of blender (2.75a) and it works!!! whopaa!!!
