Thanks for your help, apollogies for the delay in replying I've been
side tracked!

In my version of wxVTKRenderWindow.py that line isn't there, however
adding the line doesn't seem to brake anything, but equally doesn't
fix much! I did find the following at the top of the file:

if wx.Platform == "__WXGTK__":
    import wx.glcanvas
    baseClass = wx.glcanvas.GLCanvas

Commenting out these lines did get rid of the segmentation fault,
however it did not fix the picker problem. It's still getting crazy
coordinates which would place the mouse cursor at the top of the
screen and a few offices to my right!

I'm currently having a look to see if there are any RPMs avaliable of
a more up to date version of wxPython/wxGTK. My software is the most
up to date avaliable through FC5 software updater.

Thanks again for the help,

Wesley Brooks.

Python 2.4.3 (#1, Oct 23 2006, 14:19:45)
