I'm very new to programming the Amiga and I have a question
which I couldn't find an answer to in any of the books I've
looked at:

How do you make a hardware sprite disappear without doing FreeSprite() ?

Is there a safe and sanctioned way of doing this?  I can think of
some ways but they seem like kludges.  I guess a related question
is: is freeing it the best way to go?  I'd rather just acquire a
hardware sprite in the beginning of my program and keep it until
the end, making it pop up and disappear when needed (it's just being
used as a sort of pop-menu attached to the RMB - it never changes
shape, etc.).
 
So - should I be doing GetSprite(), FreeSprite() all over the place?
Should I be doing a ChangeSprite() to point to a block of 0's?
Should I MoveSprite() outside the bounds of the ViewPort???
Could I set the height to 0????????
The first way seems more work than necessary and the last 3 sound
like kludges to one degree or another.
