Re: Self terminating popup window - need help

That¹s because the run loop is still running, I think.  When you close the
window, you might want to try stoping the run loop.

Look up NSRunLoop  in apples developer documention.

Instead of uisng 'run'  you could use:

runUntilDate:(NSDate *)date

And provide a NSDate of when the runloop should stop.
