i have used Thunderbird email client in the past and it always worked flawless. However, for the last year, after I installed it on my new laptop and desktop, it is very unreliable and unstable. It downloads email messages ok, however when I open the email, it freezes up, becomes unresponsive. it looses the ability to scroll in open emails. it is about the worst thing since the email client released by Microsoft. Matter of fact, it is more unstable. What happened to my once "go to" email client? Somebody please help. The way it functions right now, I may uninstall it and use Gmail from google, less aggravation.
