Not the exact same problem, but mine does this occasionally. ONLY with the soft top though.. doesn't make sense! With the hard top on it never happens, but with the soft top sometimes I will open the door, go to close it and the window will get stuck on the top and not seal. If I open the door again it goes down and will then seal when I close the door. Any help?
