   Hello Jens,   
      
   As you have not mentioned how you did what you tried it might well be some   
   of my suggestions will be what you already know and have done.  In that   
   case, don't blame me please.   
      
   A couple of things:   
   1) Direct memory access (fastest there is)   
   2) Draw synchorised with the screen,.  I seem to remember an INT which will   
   only return when the drawing of a single screen is completed.   
   3) Do not save the *whole* screen, but just the part which gets overwritten   
   by the mouse.   
      
   Hope that helps,   
   Rudy Wieser
