Problem - Thunderbird Gmail Norton

[king1]

The original problem at the beginning of this thread started after a Thunderbird update  and resolved when a Windows update came through. So although I was open to suspecting Norton being the problem, I have no real evidence that it was.

Could be, equally possible Norton pushed out an update in the background and it wasn't until the restart for the windows update that it took effect...  One of the irksome things about IT is that it is quite often difficult to pin down exactly which component has failed on you - sometimes you just gotta take the win when it is back to normal...
