I am doing all these things. The problem I am having is that the mouse is not
behaving consitently with each window I open. WHen I open a new window, the
mouse travels to the lower right corner. I have to move my pen away from the
tablet giving control back to the mouse. Then after I do a mouse operation,
I sometimes get control back to pen. I thought it might have to do with layers,
but I am not sure, now. After I do a mouse event, I close the message port 
and reopen it for the next event.

I think I am doing this when I close the message port and reopen it for the 
next mouse event. Thanks.
