Ok, I have my problem simplified down to this...
I have a double buffered display, and an animated copper list. Now for the
problem:

The animated copper list requires this...
vp.DspIns=vp.SprIns (etc...for the ClrIns and SprIns)
then a FreeVPortCopLists() or it eats memory...
then I restore the variables and do a MrgCop, then a LoadView...

That's the problem, doing a MrgCop kills my double buffering...
I just can't draw into the rastport that points to it...
Anyone know where my RastPort is going?
(I know that it is switching, because if I put a RectFill in one it blinks)
(If I put a RectFill in the other, it never appears)
(They BOTH(the bitmaps) work if I don't do the MrgCop...)

thanks...
