@Jonathan It seems to have "remedied" itself. I don't know if you had a hand in that... but, cheers! Suggestion...Would love if the window was collapsible, instead of just getting lost in the mix... like a dock "Popover", or a menu bar item or something??

I am stuck in a state where it says "you are being returned to stack inbox" in one window, have spinning cogs in the main window, cannot "clear cache", and my life sucks. any advice?
