Couldn't you use NSResponders method? NSWindow is a subclass of it.

- (void)mouseDown:(NSEvent *)theEvent

You could also try using this method.

- (NSEvent *)nextEventMatchingMask:(unsigned int)mask untilDate:(NSDate
*)expiration inMode:(NSString *)mode dequeue:(BOOL)flag

Just make sure that inMode is NSEventTrackingRunLoopMode (the method you are
using actually calls this function with no expiration and inMode as
NSDefaultRunLoopMode. Try it the way I suggested (look it up in
NSApplication's reference to get all of the possible values for all of the
parameters).

Hope that helped!
