Usually at the bottom of the Thunderbird Screen (24.5) on the left hand side there is an icon/function that shows the accounts being checked when you press Get Mail. On the opposite right hand corner is a count of messages. Well now Thunderbird on my PC (Win 7 Home Premium 64 Bit) will only show that situation if I open it with all add-ons disabled. Otherwise the message count appears on the left hand side and nothing on the right? I have tried switching appearances, even using the default, but clearly one of the add-ons is causing the problem. Apart from laboriously disabling one at a time had anybody worked out which add-on causes this problem?
