opaque white rectangle in lower corner of screen above taskbar


Laurence Smith

For the past few months I have frequently found a solid white rectangle
that sits above the task bar in the lower right corner of my screen.

I can't determine what program or process is causing this and about the
only way to get rid of it is to reboot the PC.

Has anyone else experienced this and would anyone be able to hazard a
guess as to what may be causing this annoyance?

Clicking on it and right-clicking has absolutely no effect.

(I even had to post this message from my laptop since in Xananews the
OK and cancel buttons in the lower right are obliterated by the white

Run the Microsoft Sysinternal Process Explorer Command

In the toolbar you will see a black "target" icon or it can be
described as what looks like a fan.

When you mouse over it it will display "Find Windows' Process (drag
over window)"

That's what you do. You click on and drag that icon on tp of that
"...solid white rectangle that sits above the task bar in the lower
right corner.." and it will take you baqck to Process Explorer and
will show you what process is responsible for it.

Thanks for the tip.

About an hour after I posted the white rectangle disappeared almost
like it was a pop up whose time had expired.

The next time it shows up - and I am quite sure that will happen - I
will follow your advice and try to learn what process has caused it.

Again, I appreciate your taking the time to reply.
