Self terminating popup window - need help

Hi,
  I created a subclass of NSWindow that automatically closes the
window after three seconds. The subclass works as it should when
called from a normal objective-C routine/function. However, if I call
it from within a NSThread I create, it will popup but not close. Does
anyone know why it won't work porpperly when call from within an
NSThread?




---------------------------------- Custom NSWindow class
--------------------------------

- (id)initWithContentRect:(NSRect)contentRect styleMask:(unsigned
int)aStyle backing:(NSBackingStoreType)bufferingType defer:(BOOL)flag
{
   
   NSWindow* result = [super initWithContentRect:contentRect
styleMask:aStyle backing:NSBackingStoreBuffered defer:NO];
    [result setLevel: NSStatusWindowLevel];

    [self performSelector:@selector(closeSplashScreenPanel)
withObject:nil afterDelay:3];

    return result;
}

- (void)closeSplashScreenPanel
{
[self release];
}

---------------------------------- NSThread Stuff
---------------------------------------------
[NSThread detachNewThreadSelector: @selector(MyThread) toTarget:self
withObject:nil];

- (void)MyThread
{
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

             
                    //Programatically Create and display window here
                    //in my actuall program I have a hole bunch of
stuff running in a while loop
   
       
[pool release];
   
}

Any help would be great,
