The funny thing is that in WonderBrush, when I draw something with my
tablet, the mouse tracking is much more jerky in Haiku than in ZETA or
BeOS. (I am going to post screen shots I guess.) We must be doing something
wrong. At least we are definitely not compatible with BeOS apps from a
behaviour point of view.
