John,
I've tested this only in the Graphics dialog, but it may also be in other dialogs: Depending on the "something changed" state, the bottom right button of the dialog is either [Close] or [Cancel]. The "Close" string requires less space than the "Cancel" string and the result is that the [OK] and [Apply] button dance back and forth sideways when the "Close" is changed to "Cancel" and vice versa. It's only a tiny thing, but it looks so uggly. Cheers, Rob.
