Hard Disk Monitoring

One user reported similar in some weeks and did the best - but could never reproduce the issue. Runned the software on test systems for very long time, many weeks - but never saw anything, the focus never lost. Did monitoring with window-focus-logger tool which never reported any loss of the focus....

Sorry to revive an old thread, but this is still an active issue that losses focus on all windows, as well as it minimizes or pops out full screen games.
A dumb solution to a problem might be just to make a task inside Task scheduler, so it kills hard disk sentinel right before midnight
