Our current windows pivot in the middle which makes a fixed screen impossible.

(They do have a "pane inside" mode which would let you put a screen on the outside but we're 3 floors up and it would be a bit tricky, not to mention inconvenient when the temperature drops.)

I can see this being an issue, though everyone I know has some variant of the standard "German window" (https://2.bp.blogspot.com/_gv8PbeT2Ktk/TDiZRMA5oGI/AAAAAAAAA...) where they work fine.
