[PyQt] Some of the demos not working

[Girish Joglekar]

I installed PyQt-4.11.4 on a Windows 10 64-bit laptop. I tried all the
demos using py qtdemo.pyw. I also installed PyOpenGL 3.0.2.

For some demos I got a message the Python.exe crashed.

The OpenGL demos did not run at all.

Is there a fix for these demos?

Thank you.
