[wxPython] How to force a frame to be active?

win2k tries to prevent windows from stealing the focus when they popup.
Instead the button in the task bar flashes to indicate the window wants
attention. I mostly like this feature.

But.... When I click on a mailto link in a web browser, I want my
wxPython-based email client to popup its compose new message window and
grab the focus from the browser. Other mailers do this so I know it is
possible.

I can't seem to do it with wxPython. I've also tried several methods
with win32gui but the best I can do is make it flash the taskbar button.

How do I force my frame to be the active one?

Thanks
