Need Help! W/Drivers Door Window

[Jaxonalden]

My drivers door window on my '04 Boxster S will not stay down (1/2" for top seal clearance) with the door open. It will only go down with the door handle held up. Once released the window goes all the way up which means its next to impossible to close the door and have it latch. The passenger door works fine.
Any help will be greatly appreciated.
