Please refer to the stripped down example script below. When I run this in OS X the menubar behaves exactly like you'd expect it to. In Windows however there is a noticeable lag (~4s on my 2GHz Core 2 Duo) of the rendering of the 'Slow' menu item. This doesn't feel right at all, to have an application show the good old (Not Responding) warning isn't exactly the behavior you'd expect after clicking around in a menu.
Has anyone run into this problem before? Am I doing something wrong on Windows side?
As far as versions go, I tested both with the latest stable, 2.8.12.1, and development, 2.9.2.1, and I am running Python 2.7.

I posted this on the wxPython list later on, and got this reply. Nothing wrong really, just XP being XP that's all.
