opencv+wxpython MenuBar very slow

[mamik]

i get code face detection from this site http://www.lucaamore.com/?p=638
and i have edited and combine with wxpython.
why the MenuBar very slow to show like this Screen Shot?

Probably because the face detection library is blocking the event loop
so the menu (and other things) are not able to process their paint events.
