Strange window behavior after stereo install?

Now, when I open the door, the window goes down slightly (as usual), but doesn't go back up when the door closes. If I continuously open and close the door, the window keeps inching down until it's fully opened. Any ideas what caused this and how to remedy?

Thanks!
