Thunderbird stops responding whenever I attempt to close the program. If I click on the 'X' top right or rt-select >close window, from the task bar the Thunderbird window either turns white and freezes and reports that it is not responding. Then Microsoft asks if I want to wait or close the program. I have tried waiting but there's only so many hours in a day! I have also been having problems lately with loads of emails that should be, and previously were junk appearing in my in box; a load of salicious emails. I thought the problem was with the trash folder but I deleted the trash folders and tried to install a new trash folder as a sub-folder of my inbox but the small install window froze as did the main Thunderbird window. Now I no longer have a trash folder and after several reboots Thunderbird continues to freeze and does not respond. I removed both Google Chrome and Thunderbird and re-installed them without any apparent result. I have shut down all extensions. And would appreciate your help in getting Thunderbird up and running again. I am running a two year old HP Pavillion 64 bit with Windows 8.1
