Help! Window goes up; then 1/2 down - stops

This is a good one..

Just shut the car off; hit the window button to bring it up. It goes up, then goes down half-way and stays there. It won't stay in the up position. Tried this a few times with the key in , the key out. The car running, the car off, etc. Same result.

Not too thrilled with this as I leave this car in my driveway.

Anybody??
