[pygame] Window move oddity

[Aaron Maupin <maupin@xxxxxxxxxxxxxx>]

I'm currently working on a simple platform game engine using Python 
2.5.2 win32 and Pygame 1.8.1.

The main character's location is defined by x and y floats.  The levels 
are stored in a tree format to allow for vast open spaces.  Nothing 
ground-breaking.  I've been working on the collision system.

In certain situations, moving the game window (800x600) on the Windows 
desktop sometimes causes the main character to teleport upwards on 
screen to the next available platform.  Does anyone know if moving the 
pygame display window sends some kind of event to Pygame?  Printing all 
events in pygame.event.get() reveals no event occurring when the window 
moves and the character teleports.  It doesn't always happen, but when 
it does it doesn't matter if I move the window 1 pixel or across the 
desktop.

Where the character teleports and how is obviously because of my screwy 
unfinished collision detection, because if I comment out the collision 
detection calls the oddity doesn't appear.

But I just wondered if anyone knows why moving the window would trigger 
anything?
