Windows 8 Mouse is Freezing - Solution

My wife got a new laptop with Windows 8. She hates it by the way, and what little I've seen of Windows 8 I can see why. The UI is not intuitive, especially for someone with years of Windows experience going from DOS to Windows 95 to XP.

Be that as it may be her mouse/slidepad kept freezing. She solved the problem, up-to-now, by rebooting her computer. Last night it froze and rebooting wouldn't start it. Of course I was dragged in to solve it. The long-and-short of it is:

PRESSING F5

SOLVES IT!

So much frustration for nothing.
