We are familiar with one situation of the debugging error
appearing on some people's screens.

What that is is a Visual Basic program that runs on your computer
and displays those errors -- like what a programmer would use
to see bugs that don't really hurt anything but that are in a
page somewhere.

You would probably never know you had this until it shows up like
this. If you just say "No" to the question it asks, you should be
fine.

For reference, you may want to tell us what page it was on so we can check it out too.
