Matplotlib/Pylab... A Couple Of Problems...

Hello NG,

    first of all, I would like to thank you a for your kind support. I came
across a couple of problems using Matplotlib/Pylab, and I would like to
ask if someone else has encountered them or if I am missing something.

First of all, I am on a WinXP, with:
- Python 2.3.4
- wxPython 2.5.3.1
- Numeric 23.7
- I use WXAgg
- Matplotlib/Pylab 0.72.1

Problem 1:
I have downloaded the examples at:

http://matplotlib.sourceforge.net/matplotlib_examples_0.72.zip

If, for example, I try to run the keypress_demo.py, and if I resize the
window "too fast" (but it's not really fast, is just a normal resize), I
get an unhandled exception like:

"An unhandled exception occurred. Press "Abort" to terminate the program,
"Retry" to exit the program normally and "Ignore" to try to continue."

No matter which is my choice, the window crashes and I get the usual XP
message about sending error messages to Microsoft and so on. It is a strange
exception, if I resize the window VERY slowly, there is no exception (usually).

Problem 2:
Considering always the keypress_demo.py, if I run it (without resizing the
window :wink: ) and I press the key "g" (for the grid), the grid appears and
suddenly disappears. I opened the keypress_demo.py and I commented out the
draw() command (that follows the grid() command), and now the grid does
not disappear. What could be the problem with draw()?!? I have to use it
in my application, but I am not able to display the grid...

Thank your for every suggestion, and sorry for the long post.

Andrea.
