I read about it in a readme for a game, don't know which (No GameStudio-Game!). In this readme it said, this is a problem with the keyboard-driver, and they "working hard to solve this problem"

So, I see only the solution that one player plays with joystick.

Perhaps this post will get me points for originality at least.

Check out Dungeon Deities! It's amazing and will make you happy, successful and almost certainly more attractive! It might be true!
