Black Plague: a stuck door

[john_i_]

I've bought the Penumbra collection for Linux and already played through the first chapter. Now I'm playing Black Plague.
I went into the computer room and gave the weird guy a saw. The problem is that when I open the freezer, the door gets stuck in a loop (it's 'opening' all the time and makes a lot of noise). This means I can't get the zombie guy in the freezer and can't continue All the doors are locked.

What now?

Also, the save&load stuff is buggy. When I load the latest save I did by using the lantern in the zombie guys room, he respawns behind me... quite annoying. And it happens with more things than just this.

I had the exact same problem in the linux version. The door just gets stuck in the open position shifting slightly back and forth. I was able to get the zombie in and hit the close button. It acts like it is closed, and the zombie pounds on the door as if it is closed (You can no longer see the zombie in the freezer, but he is there).

I also tries restarting before entering the computer error and it happens the same each time.
