The side sliders drop, about 1/16" so the window doesn't readily
I've pushed the window back up and tightened as much as I can but a
couple of openings later it drops.
I don't know what the screws actually screw into.
I've though about just making a "'prop" from the bottom of the frame
to the bottom of the slider so the weight is taken by the "prop", or
use a self tapper below the slider as a stop?
Any suggestions before I wreck the window?
Top hung window sliders are the sort of thing I've got. Should I get
some "super screws" 19mm?
