Many thanks for all the help recieved.  The answers fell into three
categories :-

1).  Use SPRITE_OFF and SPRITE_ON macros.  This would be fine, but my friend
     is using sprites that I didn't tell you about (sorry).

2).  Use SetPointer() to set the pointer to either a null, or an invisible
     image and then ClearPointer() to restore it again.

3).  Use GetPrefs() to get a copy of preferences, SetPrefs() to reset the
     pointer to a null image, and then SetPrefs() at the end to restore the
     original (I hope I got that right).

Methods 2 and 3 were tried, and he decided to use 2.

I did send email to the first two people whose answers I received by private
mail, but don't know if it got through (Chuck McManis & Randy Anderson).
