   Sprites:  We've gotten physical sprites to work, and can move a couple
of them around with no problem; using the WaitTOF() and MoveSprite()
it is real easy.  Unfortunately we are experiencing flicker.  WaitTOF
(wait until top of frame passes) should synch our sprite with the display
so that it doesn't get cut off by the raster line, but the sprite is
still flickering.  Even Forbid() and Permit() around the entire program
(in case the kernel procs are interrupting) doesn't help any.
   Another problem:  VSprites.  Can't get these things to work at all.
The RKM is very vague on how one actually goes about defining these.
We've followed what info was given, which I think consisted of linking
it into a Gels structure, but there were many ambiguities and the acid
test -- running the thing -- produced a lot of smoke...

   So does anyone know of a good reference work on sprites or the
graphics lib.  Neither the new Addison Wesley RKM, nor the Commodore
one seem to cover it in enough detail.  Thanks for  any help.

Oh by the way, to the person who was interested in more forums for
discussing Amiga stuff:  Try Bix.  There are lots of Amiga developers
on that network too.  Contact BYTE Mag for info.   PS: No one on Bix
seems to be able to convince VSprites to work either.
