It's OK; we know about this one. Actually, it's not a bug, but an honest
to <name your diety> feature that the programmers worked hard at to put in.
Because of speed and memory limitation (mostly speed), visual effects are
disabled when your screen is using 2 or more bits per pixel. You can get the
visual effects back by pulling up the Control Panel and using the Monitors
cdev to set the display back to 1 bit/pixel (2 color mode).

The default wipe is "Plain", I think. This just plops the new card over the
other, with no effects other than the one inherant in a BlockMove().
