I had a user last week that was using a shared PC with dual monitors.
Someone had moved the taskbar for the left monitor to the right one, so the user lifted the monitors and switched their position so the taskbar was on the left side.
After 2 days she called me to complain that that her mouse wasn't working, because she couldn't get it to travel onto the display on the right side.
... Oh well, it pays the bills.
