Quartus II 13.1 and Modelsim-Altera hangs on Windows 10

I run Modelsim-Altera from inside Quartus. Modelsim fires up and seems to run fine. The transcript file looks ok. The program just hangs, and I never get it back to the point where I can specify what waves to watch, etc.

Any help? I'm not even sure where to look to figure this out!
