wont respond to keyboard up left and space, at the same time

[Geneve]

Just ran into this problem aswell . Got an expensive Dell laptop, pretty new, top-notch...... but in my game, I can't jump to the left and shoot (up+left+space).... all other directions works, like jumping to the right and shoot (up+right+space). Of course, replacing space (shoot) with any other key works... but meh.... not comfy to shoot with any other key..... guess I have to add some sort of set-your-own-keys in options.

In other words, on this keyboard, space will not work if I hold left and up on the arrow keys.... but ALL other combinations works.
