As far as I know, the (I hesitate to say) "right" way to blank the mouse is to
install a VBLANK interrupt, toggle one of the custom bits (if memory serves,
it's DMA_SPRITES or some such…I'll have to look it up and my Amiga isn't up
right now). You'll also need to WaitTOF() inside your vblank to avoid that
nasty sprite band if you happen to have a tall pointer at the bottom of the
screen.
