"Red" Mouse and stuck in a level (Overture)

[plutomaniac]

I started playing Penumbra today for my first time and I keep having an issue. After some minutes, I don't recall pressing something, the mouse changes and becomes red. Actually the mouse is now everywhere and it is really hard to control the camera. It is like a debug or developer mouse mode. It happens after playing the game for about 5-10 minutes and I have to Exit and enter the game again in order to make it go away.

I'm also stuck in the electric fence level(at the Workshop I think). I can't pass this fence because the barrels won't do me the favor to go there. Here is a small video of both issues I'm having:





PS: I could only record 30s with Fraps so sorry for the ending. I didn't manage to pass the barrel of course.
