Touch Screen Flipped

Hello All, 
      I guess its a well know problem when everyone install the ready WinCE
OS provided in the friendly ARM CD, ie the touch screen is flipped. 

The solution which is find in all the forum is that I need to calibrate the
touch screen using mouse. I am not able to get the exact procedure how to
calibrate touch screen in WinCE using mouse. Please guide me regarding the
same.

Plug in your mouse, then click Start---Setting---Control
Panel---Stylus---Click on the "Calibration" tab then "Recalibrate"

Thank you for your response. After calibrating, touch screen is working
fine.
