This tool does nothing except emulates a bad application... It can only change process priority class, start an endless loop (i.e. stop responding) and crash its process. In addition it can flash window and terminate shell process.

It was written it just for testing purposes. You can examine it with system utilities which always have a need for task response - task and desktop switching, preview making, minimizing to tray, etc. Source code included.
