Windows 7: Freezing busy cursor

This is a slight annoyance that seems to keep popping back up.

The cursor that turns to a teal circle when busy freezes after using the computer for like 3 minutes.

I don't know why this happens, but cycling the cursor scheme temporarily fixes it.

This is the cursor I'm talking about: Windows 7 “busy” cursor misses a beat - istartedsomething

Does anyone know what the problem is?

I'm having the same problem on my wife's laptop. The computer boots just fine, but anywhere from 3 minute to 3 hours, the curser will go "busy" and programs will start to say "not responding". CTL-ALT-DLT won't work, nothing does anything. Left it overnight once, still stuck in the morning. The only way I got it to go away was by manually powering down. Then on reboot, about half the time it wants to run scan-disk. Then, if I do anything, it freezes again. Not sure where to go from here, but I"m about to throw the thing through the wall. I built my desktop myself...figured I'd try a "brand" name...yup, big mistake. Never again will I buy a computer that I don't build myself. Running a Dell Inspiron 1545, Intel Duo-core with 4gb of ram. Any help would be greatly appreciated.

I have the some problem with cursors in Windows 7. When I cycling scheme, cursor returns back to normal arrow, but if goes my NTB to hiernate and its later return back to win, the cursor changes from arrow to busy circle. Where the problem is?
Thanx.
