I am also having the same problem for abbout the last week or so. I ran spyware and virus scan but nothing has helped.
I am having an unusual problem with my Windows XP computer. Occasionally when I am on a web site (any web site) all of a sudden the web site will disappear and the desktop will show up. Actually the whole browser (IE6) disappears. Can anyone figure out how to fix this problem? Thank you very much.
