Strange problem with FileBrowseButtonWithHistory
I have encounter a strange problem with FileBrowseButtonWithHistory in combination with wxRadioButtons. The attached self-explanatory program is a small wxPython application for demonstrating the problem. Is this a bug in my application or wxPython?

I have used FileBrowseButtonWithHistory before but this problem occured when I added wxRadioButtons to the app.

(I’m using python2.2.2 & wxpython2.3.3.1 on win2k/winxp)

Thanks for any help!

I can't see a reason for this to fail. I worked a little at debugging it, and whittled out a smaller demonstration of the problem. This eliminates all the events-handlers and the change callback. It also eliminates the intermediary panel from the equation.

Enjoy,

Would a wxRadioBox work better for you. Try this:
