I recently installed Thunderbird on a new laptop - my old laptop was running on Windows 7 Professional and Thunderbird worked perfectly. Now that I have installled it on my new laptop running windows 8 Professional, It seems to freeze for up to a minute if a new message is downloaded or a new message is being sent or you click on a different message in the inbox from the one you are currently viewing. How do I fix this? Is it a POP / IMAP issue?
