Window on Boxster doesn't drop enough to open door

[Boxter2002]

Hello everyone,

My Porsche 2002 Boxster passenger side door window doesn't drop enough to open the door without the window hitting the roof. The window does drop, and it can roll all the way down, it just doesn't go down that extra 1/8th of an inch to make it a clean open, is there a way to adjust this?

Thanks
