Tracker disappearing is only a symptom of a larger problem of loosing several work environment settings. It is not completely random as thera are some conditions in which it happens 100% of the time (ie, every time you drop in a DWG, etc, the WE settings are lost. Maybe also launching a new instance of AC also does it)
This has been going on since AC version 10, which makes me think that if they could not fix it in a version upgrade, a hotfix patch ain't going to catch it either. It is maddening and has been noted here several times before.
