Something odd has been happening on my desktop computer.
At intervals (it appears to be once an hour, at about the :45 mark), a small, empty, and transparent frame appears on the (primary) monitor; it grows rapidly, to perhaps 20% of the screen, then vanishes. The event takes less than a second, so I haven't been able to catch what process is involved.
Should I be worried?
ETA: I now find that, for that split-second, it also grabs focus.
