When typing an email.. Thunderbird "locks up" and stops typing.... Often says [at the very top of the screen on the left] "Program not responding".... I just installed Office365 and the Microsoft Techs had to put in a "new" Windows 7. THAT is when the problems began. I have installed software to "clean the system" and regularly use spyware remover.
