windows and viewpoints

[hotspur1]

I'm having trouble running the viz_windows.py demo script with v2.09 - I get an error in parsing the file that

Traceback (most recent call last):
File "<string>", line 2, in ?
File "viz_windows.py", line 26, in ?
UpperLeftWindow.setposition(0, 380)
AttributeError: 'NoneType' object has no attribute 'setposition'

Somehow it doesn't seem to initialize the wondow object properly. Any hints?

Also, say I am running in 1280x1024 mode and I open 4 windows each sized 640x480. Am I still rendering 5 scenes, even thoug hone of them (the main one) is occluded?

Thanks
