Yes I worked once in Help Desk support on call. What the heck! who doesnt?
User: Can you help me I have just patched my system and my "bills to pay" screen is frozen.
Support: How frozen is it? Is windows still running?
User: How can I now that?
Support: Can you move your mouse?
User: Yes, I can...
Support: Ok, sounds good, your system isn´t totally broken.
User: ...Sir, I dont know if this is important but the pointer in the screen that uses to move at same time as the mouse isn´t moving.
(duh)
