This reminds me of how in Windows 95, installers would complete quicker if you constantly moved the mouse, but would take longer if it was still.
I discovered a bug in a microsoft software installer where it would hang unless you moved the mouse over the progress bar. Discovered this when trying to use a java api to make silent installers for programs that didn't have them. The solution was to use the java api to move the mouse back and forth over the progress bar.
Oh the memories of playing with java.awt.Robot...
