I've organized my email into lots (and lots) of folders and sub-folders. For example I have one folder for tech support and it has subordinate sub-folders for all the tech companies I've corresponded with over the years. Extensive use of filters helps most of the sorting to folders get done automatically on receipt, but occasionally I'll get a message in my inbox I'd like to move to an appropriate sub-folder .... say, a tech support company. So ... with my inbox index in the main message window, I find and drag the desired message over to the sidebar and because the target sub-folder is (virtually) below the sub-folders listed, I carry the message to the bottom of the list and T-bird scrolls down for me .... but it scrolls so quickly and so far that it ends up going way past the target sub-folder. Having gone too far, the same fast scrolling "feature" makes it tricky to find the desired folder when scrolling back up. The scrolling feature is useful, but I need to slow it down. The two scrolling controls that are easily found in settings don't have an impact on this behavior. I looked into the advanced controls (the one micky-mousers like me aren't supposed to fool with) and I see a lot of parameters related to scrolling, but I decided not to go the way of Micky (in "The Sorcerer's Apprentice"). Can any of you Wizards out there help me.
