Re: [Visualpython-users] new version crashed on Windows XP

[Bruce S. <Bru...@nc...>]

This is unfamiliar behavior; I've seen few problems on Windows. And if 
you run an example program such as bounce2.py, or one of your own old 
programs, there should be no issues with graphics drivers, which one 
would expect would only affect the ability of your machine to display 
materials such as wood.

Here are some things to try. Please report what you observe.

Open a Python shell window and type "from visual import *".

If that works, verify that non-window aspects are working by typing "a = 
5*vector(1,2,3)" which should print out <5,10,15>.

Next try "box()" and see what happens.

To get a more detailed look, go to the "System" control panel and choose 
advanced settings, then environment variables, and create a user 
variable "VPYTHON_DEBUG" and give it the value 1.

Next, instead of using IDLE, run the Windows command prompt, found in 
Accessories in the program listings, and execute these statements:

cd c:\Python25\Lib\site-packages\visual\examples
\Python25\python.exe bounce2.py

You'll get a trace of activity in the Visual module which may give some 
indication of the problem.
