First I thought it was only GIMP... But now it seems there is almost no drawing program that works for me. Only paint.NET and perhaps photoshop elements work. But both of those aren't exactly perfect to work with.
Sigh.
I really hope this will be over soon because I'm not feeling like handing my laptop over to some computer dude who will probably put a shitload of other programs on it. I just want to make some pages for my webcomic. Is that too much to ask? :c

Oh btw, here's a list of programs that I already tried but sadly don't start / install:
GIMP 2.6
GIMP 2.8
Paint tool SAI
Firealpaca
Adobe Illustrator
MyPaint
