Yeah, I had the most problems when switching from 640x480/256 to 640x400/Thousands mode on PowerBook 5300c's. Every time I went from x400 to x480, the Control Strip would bump 80 pixels up. If I changed a few times, I might end up with the Control Strip at the top of the screen!
(This was back when the 5300c was fairly new, and I liked to watch movie trailers in Thousands color mode, which required the lower resolution.)
