I did install Firefox last night, but it made no difference.
Now here's the kicker!!!!
This morning when I booted up, everything worked. I assure you, all the problems I reported over the last several days were real. But right now web shield is on and I'm able toaccess everything, including email!
The problem (and there is one) must be on my computer. I've had other little glitches like this, and I suspect this one will return again. I really feel a clean install of XP is indicated.
Thanks again for all the generous help!
Cheers, Don.
