Hello, Sorry to be a pest with this, but have always used Thunderbird, and this is driving mer crazy. Always worked fine, until the last rev., or so. Now, continually get that rotating colorful ball, usually forever. Sometimes does go away after a minute or so, sometimes never. Never used to have this ball, and hangups. What is going on, please ? Suggestions for having it work, again, as in the past which was perfect ? Thanks, Bob
