Re: NSTimer question...

Are you running this in a modal panel, or in the context of some 
other processing?  scheduleTimer... method adds the timer to the 
default runloop mode, which doesn't fire in modal panels, event 
processing, or other custom modes.  You can use NSRunLoop's 
addTimer:forMode: to specify other modes. Note the special mode, 
(NSString *)kCFRunLoopCommonModes, which represents the default, 
modal, and event processing modes, as well as any modes registered as 
"common."
