SetHidden on two objects... Slow to hide

FROM : Trygve Inda

I call:

[myViewA setHidden:YES];
[myViewB setHidden:YES];

A is a spinning progress indicator, B is a text field. The spinner
disappears about .75 seconds before the text regardless of the order of
these lines.

Is the only way to hide them simultaneously (to the user) to encapsulate
them in an NSView containing object?

I would have thought that setHidden would queue them up to be redrawn the
next time through the loop and thus they'd vanish at the same time.

Thanks,
