   That is a problem that shows up on the ROM 3, and is caused by
Apple's changing of how the mouse is drawn onscreen, especially with
respect to the use of the 'shadowed' Super Hires screen which was
added in System 5. [Tech details: if shadowing is on, programs must
write to bank 01, not just E1.] Fantavision should be old enough that
the OS should default to the *safe* cases, but that's apparently not
the case.

   Solution: rewrite the program, or run the program on the *more
compatible* ROM 01 machine.
