Spur and looking down problems

I wonder why I can't move left and jump at the same time when charging my Spur and whenever I jump looking down, I can't shoot using any weapon?

 

It's likely a problem with your keyboard. Try setting your game to <>? mode in DoConfig.

 

Same problem. I also tried it on my older computer (which also has the game in it) and the same problem occurs.

 

Are you using a laptop? Because that's probably the issue.

This isn't an issue with the game, this is a problem that's more commonly known as "key ghosting". It's an issue that's more common/present in laptops. You can read more about it here: http://en.wikipedia.org/wiki/Rollover_%28key%29#Key_jamming_and_ghosting

 

Okay, that makes perfect sense, then. Thank you.
