First Porsche need held please

[Slowie]

Hello everyone.

really happy with my first Porsche i got a black 2004 boxster with 100,000 with full service history. the issue im having is that the drivers side window seems to have 2 issues and im pretty sure they are related.

1. the window doesnt drop when opening the door. from both inside and outside handles
2. the window will open when i press the button to fully shut it. the first time I press the up button it goes all the way up and then goes halfway down straight away. the second time it goes up and stays up.

its had a new regulator fitted in the last month I'm just wondering if it was fitted wrong?

Any help will be greatly appreciated ill try and get a video up of the issue tomorrow (as its 2am here)
