Re: [Visualpython-users] Bug in Visual 5.1 on Vista when more than one window is opened

[gelfand <ge...@la...>]

The graphics driver (for Intel video) is the most recent release from Dell.

Both waves.py and controlstest.py show the "bad" behavior as well. For
example,
in waves, only the middle window actually displays a wave, the upper and
lower
ones (corresponding to 2.0 and 0.5 kg mass) are empty.

Any suggestions for further debugging, or is this definitely a video driver
issue?
