Slightly embarrassing situation. On the upside I'm 99% positive that I know the solution. Situation: I somehow without knowing it, used a keyboard shortcut that closed the main toolbar (You know with esp/esms, factions /etc/). I one time closed the item window without knowing it before, yet somehow reopened it. I'm nearly positive this is happening only with the main toolbar this time, because I'm ignorant of the keyboard shortcuts, that toggle these things on, and off. I just require the keyboard shortcut to open the main toolbar, I've done several google searches, and can't find what I'm looking for. I'm kind of shocked that no google results are saying anything about these specific keyboard commands.
I require the keyboard shortcut to reopen the main toolbar that I somehow closed, or I can't do anything, because I cannot even access esms or esps now.
Edit: Resetting my computer fixed the problem somehow.
