Sounds like the window has come loose from the regulator, a common problem with our year cars. The rear part of the regulator will come unglued from the window causing it to push the rear of the window up and then it will not sit in the door gasket but a little above it. It extreme cases it will hit the roof.
To check take the door panel off and roll up the window and if it is loose you will see what I am talking about. There are several fixes for this, one is to but a new window and regulator (the expensive option). Another option is to re-glue the window to the regulator with some window adhesive that you can get at just about any auto parts store, (3M makes the best product). I went a little further on mine so I don't have to worry about it repeating itself.
If the window is loose you will see that the window stop is located at the rear of the door and it stops on the rear of the regulator, when the window is loose this causes the regulator to pivot on the rivet that attaches the track that the window sits in, therefore causing the window to roll up to much (you will see what I mean when you watch the window roll up). I drilled out the rivet and replaced it with a 1/4" nut and bolt. I then added a #10 screw and nut just below the 1/4" nut and bolt that I replaced the rivet with. The #10 screw will keep the window stop from trying the pivot the window. Then I re-glued the window to the regulator with the window adhesive.
I used to have pictures but I cannot seem to find them.....
