Hi, sorry for my english
I need help, today i started to play Mount and blade: Warband and Napoleonic Wars, in both my control is weird, when i moving a mouse it's just going in every side, i can't aim on enemy, and maybe 5-10 second it's okay and again this problem, the same when i use my kaybord, im going in one way, and then my hero is going by selv, even when i don't touch the keybord. This is my first problem like this, and i realy don't know what to do. It's look like i can have lags or something like that but it is impossible, because i have good internet and ping 40-50. HELP!

I have the same problem. It is not possible to control the character with the mouse.
Also the keyboard control is ridiculous. It doesn't respond , only when the fight is over and I#m dead.
Is there a solution?

I had the same issue. There's a thread about this called "Input Delay Problem" or something like that. It offers the solution of disabling the in-game overlay in your Galaxy settings. Apparently something about the overlay made your mouse go wonky. I never use the overlay anyway, so for me it's not a huge deal at all to turn it off.
