Is there anyway through events or some other log to see what would be unchecking autohide taskbar.

At least last 2 nights, with no new software installed but who knows what updates in background, when I get on computer the taskbar is locked to show. I go into the preferences and see that the checkbox for hiding has been unchecked. During this time no one has touched my computer as I always have it running I can confirm this today as I was the only one home most of the day and when I was not no one even went into the room the computer is in.
