I downloaded the portable one because I prefer portable versions of things if possible. I had to edit the config.json because the window size defaulted to wider than my screen and the gear icon was impossible to find, as well as the close button.
So... if someone else has issues use notepad++ to edit the "width" and "height" in the "WindowBounds" section.
Also reading other replies I see I could have just double clicked the top bar. Oh well, Live and learn!
