... I have been too early in posting this thread because...the solution was right under my nose...Endroz's GK2 installer
I at first didn't want to try that because I didn't quite like having to play GK1 in a small window when running it under XP, and most because I was afraid the bugs would still be there...
...but the bugs I mentioned are gone! Endroz, I worship you, I owe you my sanity
So...a bit sorry for opening the thread unnecessary, but if anyone ever encounters the same problems: Endroz's GK2 installer works like a charm!
