Anyway, I solved my "hard to lift" he-man windows and turned them into lady windows for $3.18 for a pair from (of course) Amazon. Took 10 minutes (including bathroom break) and worked like a champ. Couldn't mount them on the bottom because the available sash area sits into a channel and is completely covered but my vertically challenged wife (5' 0") could reach the top with no problem. No more broken nails for her and no arthritis problems for me trying to grab the 1/8" available lifting surface on the bottom. This plus a bit of silicon spray and it is 100x improved.

Yes, it now has both screws installed.
Edit: I used the 2 of them on the one sash.
