Active Window becomes inactive

Dell Inspiron, Vista home prem. This happens very occasionally. Working
in a window, pause for a few seconds and the title bar dims and and the
window becomes inactive and another open window title bar or a desktop icon
will become highlighted ("active"). I have to mouse click in the window I
was working in to reactivate it. This will keep repeating until I reboot.
Any ideas on why this is occurring and how to keep it from happening in the
future?

Another background application is probably stealing the
focus. I've made a little ugly tool which log the foreground
window. This should help to find the culprit:

It could be spyware, virus, or Trojan infection on windows. Run a full virus
scan with a good AV like avira or avast. You may need some tech support if
it is a bad virus.
