    hi, I have a strange problem .... a flashing lock/unlock icon (padlock which alternates form locked to unlocked) shows in the middle of my screen. The machine was built a few years back and hasn't changed significantly since then The symptom has just begun today - Sat Aug 6 my time) and only impacts Windows. The Linux install on this machine is unaffected I'm running Windows 7, with Office 7, both activated successfully (also running Open Office and Libre Office which were upgraded last week) I recently changed video card, about 3 weeks back suspect this is related to some sort of Microsoft security issue can't find any references on the web ... cant generate a screen shot (which suggests this is being inflicted by Windows itself) even with bitmap capture eg. snippy the icon is a very basic black and white padlock shape that stays right in the middle of the screen, is partly transparent and is visible no matter what programs are running - full screen games or windows applications I'm at my wits end with this ... no idea what's causing it or how to remove it any advice would be most welcome

    Change your resolution to another setting, apply it and then change it back. This is as per maltasama link. I personally have never had this issue.

    I forgot to say that I have already tried that. The lock/unlock picture comes back after about 1 minute.
