Your #1 fix fixed the popup issue. Got further issues, though:
The bottom menu is kinda glitchy and doesn't open all the time. The top one is an extreme version and only works once in a blue moon. I also get occassional graphical bugs around the text, and sometimes text wont appear at all, which I fix by right clicking twice to hide/get the GUI back.
I am in Japanese Locale, so it's not that =/ (Region Settings -> Administrative -> language for non-unicode programs, etc. etc.)
Edit: actually, more than a graphical glitch, is as if the game kinda freezes itself. This persists into the gameplay section (like when you select your troops), and there the right click fix doesn't work, so It's unplayable :C
