Autoclose Window

[dadidoe]

Hi,

currently I am working on a Splash Screen. It's being displayed but not autoclosed. Instead the Mac OSX "Bottle" Sound comes every 5 seconds.(that's what I set the NSTimer for)The Window is named window2.

Can someone tell me what I have done wrong?

-(void)awakeFromNib//I must ensure the window closes.
{
    NSTimer *timer;
    timer = [NSTimer scheduledTimerWithTimeInterval: 5 target: self selector:        @selector(tick:) userInfo: nil repeats: YES];//telling the Mac if the alert will repeat and what interval.
}
- (void)tick:(NSTimer *)theTimer
{
	[window2 performClose:self];

}
