Bug #225: Cross-dissolve between "Advanced" and "Hot Keys" preference panes is not smooth

If you hold the shift key to turn on the slow motion mode while switching between the "Advanced" and "Hot Keys" preference panes you'll see that they don't redraw themselves for any of the frames in the animation (you see only the first frame and then after a while, the last frame). You may not notice this when slow motion mode isn't active. The transition to and from either of those preference panes to any other is smooth; it's only between those two that you see the problem.

I suspect that this is something to do with them containing NSTableView subclasses with delegates/ datasources. There may be some way to turn off updates or temporarily disconnect the delegate/data source during the dissolve. I think this is a very minor cosmetic issue so fixing it isn't a very high priority, but I did want to make a note of it here.
