Door release cable

[sheep]

Okay first hi folks new here ive had my Boxster 3.2s for approx 6months now and loving it , its a 2000

I have a question i did a search and found nothing , my drivers door handle seems to drop back upon shutting the door , if you hold the interior handle the window goes all the way up if let it go it drops as it should to clear the roof when opening the door.

Ive checked everything i am wondering if these door release cables stretch and if there are any adjustments that can be made or is it buy a new cable , if so any ideas where i can buy one as ive searched google to no avail.

Many thnx in advance folks
