Problem Fast Painting Mode workaround?

Are there any known workarounds for the "use fast painting mode" issue in SprutCam 7?

I'm using the latest build of SC 7 on a MacPro running Parallels version 8 and Windows 7 32-bit. I'm able to run other OpenGL applications just fine (SolidWorks, Games, etc.) and the system passes all of the OpenGL tests without issue (OpenGL Extensions Viewer). All drivers are the latest version.

With fast painting mode on, Sprut will crash almost immediately with an exception error or access violation on sckernel.dll

The problem is, with fast painting turned off, I get about 2 or 3 fps performance - very frustrating!

Any ideas?

Thanks,
Kent
