I'm running Mozilla Thunderbird email client version 1.5.0.9 under XP with McAfee Security Center on a Dell Dimension. Working fine. An update notice for McAfee shows up for new version of Security Center (7.2). With trepidation, I accept. Now Tbird hangs at "connect to" for about 2 minutes before asking for my password and receiving mail (used to be instantaneous). Now I can't send mail; I get a "can't connect to" message. I can still surf the web just fine with Firefox and IE. I can't rollback the McAfee update with Windows System restore. It produces a broken version of the old McAfee Security Center. McAfee online technician can't fix it. In short, this is a disaster. Great job McAfee!!! I would appreciate any suggestions for fixing this mess.
