movement in Unity Applications is stuck

Hi - I''m new here.
I'll be working with Unity at the university next month and even now I've encountered a problem I couldn't find a solution to.

It has nothing to do with Unity coding really - it's more of a general problem I can't find a solution to: in the Web player as well as in the standalone applications the first person camera is constantly moving backwards.
I know that it worked without any problems before but for some time now this seems to happen in every Unity application. Even the Island-Demo which worked without any problems does it now.

I'm on WinXP and other applications perform normal. So it's probably not some kind of stuck key on the keyboard etc.

Did anyone else encounter that problem?

 

Do you perhaps have a joystick that's connected? This sounds really bizare

d.

 

Embarrassing - but that solved it

The dead-zone of the analogue sticks probably was set way too low.
I actually didn't suspect it, though since moving the sticks didn't move the camera. So i expected it to not respond to the Joypad at all in these apps.

Thank you ^^
