Is there a way around this?
I've tried everything it seems like.
I really think it is strange that you would not be able to place a button over 
a differently colored panel without getting weird results.
The most annoying occurance of the same problem is shown in this picture

here you can see a wxNotebook with the wrong colour chosen for it's 
background. (up in the windows-tab)
