I ran into something similar many moons ago. If I recall correctly, it had something to do with optimization of the scroll bar processing in Palm OS. It only draws the arrowheads when it thinks it needs to. By drawing a bitmap over the arrowhead, you confused the optimization routine.
To get around the problem, do a frmHideObject on your scrollbar, so that when it gets redrawn with the frmShowObject Palm OS won't think the arrowheads are still on the screen.
