I have a Simple Sprite which looks like a small white ball.
I want to move the sprite around on the screen.

So:

1)  I open a custom screen with a custom bitmap.
2)  I open a window in the screen.

Then I call GetSprite() to get a sprite to play with.  To
move the sprite, I call MoveSprite().

Everything works great, meaning my screen and window
open properly, my call to GetSprite() succeeds, and
my sprite appears onscreen.

However, when I move the sprite (ball) around on the 
screen, the previous image of the sprite does not
completely disappear before the sprite is redrawn
at the new position.  As a matter of fact, at
a higher speed, I can distinctly see 3 images
at once.

I should also note that I can move the mouse
pointer around on the screen right alongside
the ball(sprite), and the mousepointer looks
perfect.

Can anyone help me?  I'm on an A1000, using
Lattice 3.03.  I *know* that my imagedata for
the sprite is correct, and that I'm using
GetSprite() and MoveSprite correctly.  The
cursor is a Simple Sprite, right?  Is it me?
My compiler?  Couldn't be the Amiga, right? -
I mean the cursor looks great, just my sprite
is messed up.

help,
     help,
          help...
