I think the root of this problem isn't even in gui. A timer gets set up 
for the tooltip via the NSTimer method
-scheduledTimerWithTimeInterval:target:selector:userInfo:repeats:
That method uses the runmode NSDefaultRunLoopMode for the timer. While a 
modal window gets displayed gui requests events in the 
NSModalPanelRunLoopMode and the timer wont get fired. Now this behaviour 
matches the Apple documentation, but results in the tooltip never 
getting displayed.

To work around this behaviour gui should create the timer via 
-timerWithTimeInterval:target:selector:userInfo:repeats: and add it to 
the runloop itself for different modes.
