Sketchup Hanging on Start? Disable OpenGL Acceleration via Registry

My Sketchup 2013 copy suddenly stopped working right. First it would hang if I tried to add a scene, then it just hang and race the processor once it started up. I tried all the latest drivers for my AMD Radeon 7800M, but no change.

I knew I could at least run Sketchup if I could disable the use of OpenGL hardware acceleration.

The registry key that you need to modify is in this registry branch:
HKEY_CURRENT_USER\Software\SketchUp\SketchUp 2013\Preferences

Modify this registry key:
GfxUseAccelerationOnScreen

And make it now equal to 0 (it's of type REG_DWORD)

Voila!

Sketchup should now start!

Of course it'll perform very poorly if you're working with a big/complex model and you're using "View > Face Style > Shaded" or  "View > Face Style > Shaded with Textures" so remember you can switch to "View > Face Style > Wireframe" when you can get by without seeing the faces and textures because that will still perform very well.

Working without the hardware acceleration is better than not being able to use Sketchup at all.  Not sure if my problem is truly a driver problem as Tremble/Sketchup would have me believe or if it's a bug in Sketchup.
