If the issue resolves itself when you reboot the computer, the problem sounds like it may be a driver issue. If you're using a USB keyboard you may want to try an old PS/2 keyboard or adapter just to see if it makes any difference. If nothing else the information might help the devs narrow down if it is in fact a bug in the game.

I fixed it. It had alot to do with my ventrilo client and the setup settings I was using. Basically, my Push-to-Talk key was stopping my mech, so I couldn't run and talk on ventrilo at the same time. I resolved this by disabling my tilda key in keybindings and binding it as my new push-to-talk. I was unable to find the Ctrl key anywhere in the game's keybinding menu, but it still stops my mech while running for some reason. I am unsure how this issue messed up my chat, but it just seems like chat is laggy, sometimes typing strange characters and somewhat nonresponsive overall. The game is playable now, however. Thanks for taking the time to read my issue.

It's not a bug. Pressing Ctrl makes your keypress Ctrl-W instead of W. That's how you can start a leg module by pressing '1' and start a head module by pressing Shift+'1'.
