Hi- During using Thunderbird i get a lag / small 2 second freeze as I touch the mouse and start using Thunderbird, or it will occur every 30 seconds or so of using and i'll get the 1-2 second freeze but with never a crash, it always unfreezes and I can resume using. Long time Thunderbird user and I keep all of my Emails, my sent folder has a lot of mail in and I have a lot of archived folders, could I be keeping too much old mail? I do need it for reference purpose but could this causing me problem? Any help would be awesome!
