can someone shed some light on why this might be happening.
The AppKit isn't 100% thread-safe. You'll have to perform the scroll in the main thread.

thanks.

in case someone 10 years from now is searching through the list archives for an answer to this question, here's what i did...

in init:

[[NSDistributedNotificationCenter defaultCenter] addObserver:self selector:@selector(testnotificationreceiver:) name:@"ANIMALCRACKERS" object:nil suspensionBehavior:NSNotificationSuspensionBehaviorDeliverImmediately];


in thread:

[[NSDistributedNotificationCenter defaultCenter] postNotificationName:@"ANIMALCRACKERS" object:nil userInfo:nil deliverImmediately:YES];

and added the following method:

// this is called in the main thread:
- (void)testnotificationreceiver:(NSNotification *)notification
{
	[mytableview scrollPoint:NSMakePoint(0.0,0.0)];
}

i used NSDistributedNotificationCenter, because it posts to the main thread -- and does so by default too.
