For example:

"C:\MY STUFF\DIRTY.EXE" 5

This would simulate the mouse ball is dirty every 5 seconds. By default it simulates every 20 seconds.

How to close

Move your mouse pointer to the TOP LEFT corner of your screen. This will stop the program from running in memory. If you have successfully moved your mouse in the correct position, the program will close and display an About Box Screen. Once you close this screen, the program will exit. Exiting the software will allow Windows to delete the file.
