This is a known bug.  I don't know about the minimizing but you will 
lose focus on your main window.  Here is what Derek had to say about it:

Somebody once asked:

I suspect its because that message_box() is *not* a part of the win32lib
library, thus it sets the "owner" window to NULL. When Windows closes, 
it
has no knowledge of which window it was invoked from, so Windows just 
sets
focus to some window. What method it uses I don't know, but I guess its 
not
"last used". As a work around, you might need to specifically set the 
focus
to the window of your choice via setFocus(id), when message_box() 
returns.

I'm thinking of bring something like message_box into the library, in 
which
case you can have much more control over its behaviour.
