ClickOff is a program which does a daily and very annoying task for you: klick Buttons on useless notification and error-messages. So software is very easy to use:
If a message like "Are you sure you want to exit the program" shows up, you start the window-detection of clickoff and then point on the button you want to be clicked if the message shows up again, in this case this would be "Yes".
ClickOff then waits in the system-tray next to your clock until one of its target windows shows up and then clicks the desired button after. ClickOff does not need a lot of system-resources, it will only use 1 MB of memory and 0.1% of you CPU time.
