Hello and welcome to the forum.
The drivers window sounds like it needs resetting.Just put the window right down and hold the button down for a few seconds,then get the window right up and hold the buton up for a few seconds.This should give the window it's parameters and it should magically work as it should.
The starting problems could be caused by one of many things,but the main culprit is the
sensor.If you use the search facility in the toolbar at the top of the screen and type '
Sensor' it will come up with a lot of info on the subject.
.If that doesn't cure it,then it could be a faulty
Coolant Temperture sensor,a faulty Lambda sensor,or a few other things.
Have a look at the Laguna section of the FAQ and Articles section and it might give you a few other ideas.
