Hey cool. I just installed wxPython 184.108.40.206 (was using 220.127.116.11 which I installed no more than a month ago), and sure enough the toolbar buttons look great. Even better, I don't get the leaking memory error when I dismiss the window.
wx is still broken on OS X (the toolbar icons look bad).
Hmm, I use OS X regularly, but don't use the toolbars: I'll
look into the bad icons.
The toolbar icons for both toolbars look fine to me on OS X 10.3
(matplotlib 0.73, wxPython 18.104.22.168, Apple's python2.3). Perhaps
this was fixed with wxPython 22.214.171.124 ???
