Testing further ...
Maybe the hang doesn't go forever... but it hangs for a long long time for even a simple case.
Simple test case:
- make external clad wall
- make generic louvre window on wall
- Edit window, but make no changes to the dialog, press 'Submit'
- .... Sketchup Hangs for 4 minutes
- any key presses or dialog clicks over the past 4 minutes seem to have been queued up and are replayed into sketchup
