Since I uploaded the newest version of LW, I have this new problem. After a few minutes, the upload/download rates begin faltering, eventually hitting zero. The number of sources from which I'm downloading, interestingly, doesn't seem to change. I lose the green bars. At that point, none of my Internet connections seem to work and I need to disable/enable my wireless connection to get even IE started again. I've been on 5 different ISPs in different parts of the country and the behavior is the same.

Anyone???
