        I am using non-intuition screens to achieve a static double buffer
     effect.  Basically, I create two View/ViewPort/RasInfo/BitMaps, and
     then switch between them.  The switching is handled by a copper
     generated interrupt.  The views are Loaded individually before the
     interrupt switching is installed, so I know that each view is properly
     created.

        Sometimes the program works properly, but sometimes the screen goes
     totally black (no mouse pointer).  Regaurdless, when the program
     terminates, the screen is returned to the system and continues to 
     function properly.  The interrupts are definitly occurring, even when
     the screen goes black (I have checked via other output).

        Any idea what is going on?  I have tried all kinds of disable/enable
     mechanisms to avoid conflicts, without success.  

        How does LoadView work?

                                                Thanks in advance,

                                                                Wade.
