After reading a few replies to my pleas, I have tried several things.
One -   It does make a big difference when reducing the number of colors being
        displayed by workbench.  The activation response is much better
        with only four colors.
Two -   If workbench is set to a backdrop, window activation is even better.
Three - Other programs, such as Ncomm with hi-res and 8 colors have
        much smoother operation when doing activations.

Questions- Is there any way to reduce the lag the pointer experiences
           when the workbench has 8 or 16 colors other than delaying the
           activation as you mentioned?  
 
           Why is the pointer operation much smoother when running
           on another screen like Ncomm when there is also a hires
           display and 8 colors or even 16?

           And it seems like the 68030 should make up for any extra overhead
           required for the 2.0 windows.
