Hi!
I haven't been using FogBugz for long (actually it's been on and off for a couple of years), but now I'm using it to track my work on a daily basis.
I've been adding and resolving/closing cases quite regularly, but I see nothing new in my estimation history.
As I've just resolved a case, I only noticed now that there's an elapsed time field on the case screen. I haven't seen this before, and so, haven't used it.
Is this why I have no estimation history? Because I haven't been updating that?
