Well, the demo on the page looks beautiful and got me all excited. But...

[~]> python /usr/lib/python2.2/site-packages/chaco/demo/wxdemo_plot.py
Segmentation fault

I get the help window to open and the plot window opens with the title "Chaco 
Plot Package Demonstration" and some plot areas. But these are blank areas, 
where only the red crosshairs appear (no plots at all). As soon as I 
left-click and the properties tab window pops up, it segfaults.

Some system info in case anyone else sees the problem:

[~]> uname -a
Linux maqroll.colorado.edu 2.4.18-6mdk #1 Fri Mar 15 02:59:08 CET 2002 i686 

[~]> python
Python 2.2 (#1, Feb 24 2002, 16:21:58)

Type "help", "copyright", "credits" or "license" for more information

I got the wxpython package from their site.



ps. Don't sweat this one. From past experience, getting wxpython to work is an 
absolute bear (at least for me). So I'm sure the problem isn't on your end but 
is wxwin/wxpython's fault.
