	I am trying to get some SimpleSprites to work with a custom View that
I have created with no luck.  What I am doing is creating a View with 6
bitplanes (HAM) and I set v_Modes and vp_Modes to "V_HAM!V_SPRITES".  Then I
do some standard initialization of the BitMap and RasInfo structures.  Once
I am all finished, I _LVOMakeVPort and _LVOMrgCop then _LVOLoadView.  At this
point everything is going fine, and then I _LVOGetSprite number 2 and
initialize a chip memory buffer to hold the sprite image.  Finally I call the
_LVOChangeSprite function with a zero in register A0, to act on the current
View (the one I just created).

	I never see the sprite on the screen.  But if I then hit the
Left-Amiga M keys, and bring the screen behind to the front, I see the sprite
on that screen.  Why is it going to the background screen when I LoadView
my new View?

	I have tried to use the ViewPort address instead of a zero in A0 with 
no change.  Can anyone see what I am doing wrong?

	Thanks in advance for any help you can give.
