window flopping

Is there a way to tighten up the front drivers window so it doesnt flop around? It doesnt move alot but when I have my door closed and I roll it up the window attacks my weather strip. It has destroyed my weather stip and Im looking for a new one to install but dont wnat to have same thing happen to it. I searched and all I could find were for sale threads on windows.

This might help.
