ZDoom

I recently got a Logitech MX Keys wireless keyboard, US layout. With this keyboard I'm unable to change straferun direction to forward right, when using the arrow keys.
To clarify, these two moves don't work :
- while running forward (up arrow+shift) pressing the right arrow key
- while straferunning right (right arrow + shift) pressing the up arrow key
The third key press has no effect in either case. The other three directions work fine for both scenarios. When using the WASD keys the problem doesn't occur.

This happens in the three versions I have, 4.1.1, 4.4.2 and 4.5.

This is possibly an issue with the keyboard; do you have issues doing the same combination in any other game/program?

Good call, hadn't thought of that. Just tried it in Hitman and had the same issue, looks like I'll have to take it up with Logitech...

Thanks for pointing me in the right direction.
