Hello!
I've been using Thunderbird for awhile now, but have found recently it's getting a bit sluggish. I have to wait before clicking in various folders, etc as it sometimes freezes up for 10-15 seconds. Is there anything I can do to improve the speed again?
Are there any alternatives I should try?
