I think the problem is that the visible 'disabled' state only updates  
when the event loop runs again. During your long-running method, the  
Cocoa event loop never gets a chance to run. Therefore, any clicks  
are queued and get processed later -- by which point the buttons have  
been enabled again.

You could try disabling the buttons, explicitly redrawing them by  
calling 'display'. You could clear any button clicks from the event  
queue with 'discardEventsMatchingMask:beforeEvent:'.
