Hi Sarah,

Don't you want to handle a click on the zoom (green +) button rather  
than the minimize button? That's what iTunes uses to switch to the  
mini window. When I checked the message watcher while clicking the  
zoom button, the cREVgeometryCache and the cREVGeometry properties get  
set, then resizeStack and moveStack messages are sent. I don't know  
whether you can prevent the automatic zoom behavior by intercepting  
them, however.

Regards,

Devin
