After I posted the message, I was able to close the box
by clicking on the close button, without using Task
Manager. Perhaps, some processing was still occuring,
although there was no overt indication of it. Or,
perhaps running the software to post the message enabled
the close button.
I have found this problem as well. It occurred in the previous build, but I
don't know if still occurs in the new one or not. What I found was that I
have to close all other open windows before I was able to close the Scan
Completed window. Not sure what the deal is with it interacting with other
windows on the screen, but sometimes it does and sometimes it doesn't...
This has happened both in a scheduled scan, and a manual scan, so that
doesn't appear to make a difference...
