This simple utility has just one purpose in life; It sits in the system tray and counts how many times you click your mouse buttons! It was developed by request for monitoring usage patterns of "kiosk" computers.
You can set an interval for collection of the counts, for example every minute or once per hour. The tray icon can also be hidden from view. To get it back just run the program again, it's always visible for the first 30 seconds.

It saves the counters to a csv file for later analysis.
