Question: Recently all of my applications keep losing focus every minute (or so) for a few seconds (then the window gets the focus back). It is very annoying, since I'm typing most of the time and get interrupted by this behavior. Things worked fine until a week ago and I have no idea what is causing this error, but I noticed the mouse moves to a certain point on one of my screens when this happens.

I would appreciate any advice: it starts to drive me crazy...

Answer: 
I had a similar problem. The Event Log had hundreds of errors in the past hour. I just killed the parent of the faulting dll. I'll probably need to re-install the program for a good copy of the dll if it comes back.

This sounds like there may be something nasty on your machine.
