I’m sure that I’m not alone. Sometimes when I go somewhere or build something, all of a sudden, the character keeps going forward just like the W is stuck. But it’s not.
To recover from this I have to bash my ASWD keys on the keyboard (gently :P) and it’s ok. What’s causing this and how can I fix it?
Answer
This is a bug. It usually happens when I’m moving and clicking at the same time.
It has been reported on GetSatisfaction, and there is a known workaround: update lwjgl
library that is downloaded together with Minecraft.
This bug has been around for a lot of time, and it would be great if Mojang actually fixed it…
