As of about May 7th, I've had no trouble getting gmail, but have inconsistent connection problems with mail.wbcable.net. I've verified all connection settings w/ wbcable techs, verified Kaspersky is not at fault, & so it all eliminates them & leaves T'bird to be the fault. Sometimes, I fire-up T'bird, & immediately get all my email access, but at least 60 - 80% of the time I have to leave T'bird idling in the background until it finally gets my email... up to 1 hr. or more delay. I also have inconsistent email sending ability. My web speed was 55, then I dropped it to 35, & now put it back to 55 & that hasn't been the cause of my problem. Please... help me! My OS = Win 7. Also, my wife can't get her email from mail.wbcable.net . If I need to retreat to an earlier version, how do I do that & to which version? I've always been on the "Release Channel", so does that need to change? Please respond quickly, thank you, Dave
