And you noticed the same with your own Clarion apps? As I understand it,
John sees this when running Clarion applications (not only SB).

I have never seen this here on our machines (we have 15 different machines
here running all kind of OSs). I checked our records, but we have never
received any similar report (and there are quite a few thousand SB users out
there).

What Richard said makes sense. Perhaps it's something specific on your
machine? The million dollar question is what is it?
