The following works for me from 10.6 to 10.9 (I've left out code that
creates an NSSearchField, NSPopUpButton and NSTextField controls - all look
the same):
- (NSToolbarItem *)toolbar:(NSToolbar *)toolbar

You need to disable implicit CALayer animation(s):
[CATransaction begin];
[CATransaction setDisableActions:YES];
[layer setPosition:apoint];
[CATransaction commit];

FWIW: UIView sets the delegate of its CALayer to itself - one of the things
that it appears to do is to disable any implicit animations. If you add your
own CALayer to a UIView's CALayer, then you're in full control. As already
pointed out, it's easier using one of the UIView animation class method

Presuming that the firstgen iPod touch has iOS 3.x on it, it is probably

Check self.thumbImageView.contentMode - it's probably the default
UIViewContentModeScaleToFill (should be UIViewContentModeCenter). Also
ensure that the UIImage that you provide really has square dimensions. I had
the exact same issue when rotating the UIImageView of a UIButton...

NSBlockOperation inherits from NSOperation so you should be able to
