Thanks for your help in this. I had the same problem. Here is some additional
information I discovered on the problem.
Many other folks who have experienced this situation have Acer computers
with pre-installed software called Acer Lanscope Agent. ALA is a repackaging
of software by Avocent called AdminWorks Agent. Mine was version X6.
Adminworks is a network remote management tool for controling clients from an
administrator's console. See
http://www.avocent.com/web/en.nsf/AttachmentsByTitle/590551501B.pdf/$FILE/590551501B.pdf.
The Agent is meant to respond to commands from the console. So, if your
machine has ALA or AdminWorks Agent installed but is not part of a network
using the AdminWorks Console part of the package, the Agent piece is useless
and, in our cases, has caused some mischief. See page 4 of the above PDF from
Avocent.
It should be safe to just uninstall this software using "Add or Remove
Programs". Be sure to reboot for removal to take effect. Or, if you are not
comfortable with that, it can be disabled in the Services folder of Computer
Management. It is listed there as "AdminWorks Agent X6". I found that
disabling this service without uninstalling worked just fine.
Thanks for leading me to the right solution.
