I run on a mbpr and I haven't had this issue until I started using teamspeak/vent again, I have to have my hotkey for those as the command key, it's a powerful button i know to have and use as often as I'd use it to talk.. But whenever I'm running in any direction on mine craft, using W,A,S,D while pressing command, it will continue to run in that direction until I press the wasd button again. This has killed me a couple times, creeping close to edges and trying to talk, or running from enemies and end up running into blocks. Anyways does anyone know how I can change this or make it so it won't happen? I'm not going to change my hotkey to a different key, I use command key because on windows I used the ALT key and the mac keyboard is sized and a different layout to PC, so that's not an option, I use it because it's easily accessed without having to reach out of the way, and it's comfortable for my fingers. Next suggestion. ^^
