You can watch the stopwatch window to see the speed change. 2) Go to www.myke.com and look under his PIC applications/utilities page. There should be a utility called "SPEED.EXE" which simulates moving the mouse around. Run this just prior to starting the simulator and it will run immensely faster. Again, a before-after comparison using the stopwatch window will show you the gain you're seeing. --Andrew _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx -- http://www.piclist.com hint: The PICList is archived three different ways.
