Hi.
I have written a C program that will rotate a 3-D object around an arbitrary
point and display it in perspective 3-D.  The program works great.  Then I
added another section so that the IDCMP sent mouse reports to my program
so that I could read the mouse and zoom in and out accordingly.  Once I
enter my IDCMP read section, I read all the pending messages and then I
go on to the next rotation.  Then it loops back to the next read section.
What I am seeing is that the more I read the mouse, the more my program
slows down.  I am receiving nothing but mouse reports and closewindow
reports.  Why would my program exponentially slow down just by receiveing
IDCMP reports?  Please reply directly to MCARTSHA@UREGINA1  (bitnet).
Oh, by the way.  It runs faster than on a 20 MHz 286  ;-)
