Hi all. I've been trying to find some instructions online about how
to remove a frame from a single hung window and replace the glass in
it, but there is pretty much just one set out there and it's not very
helpful.

We had a storm this summer and hail broke the outside pane of the
window. The window is, I believe, single hung: there are 2 panes on
top, one inside and one out, but neither move. The bottom is one
sliding glass pane inside, a screen on the outside. It's basically a
glorified screen window.

We've replaced glass in old houses before without difficulty.
However, we've never dealt with single hung windows and we don't want
to accidentally break any mechanisms or whatever is inside these
things. Any thoughts? Thanks!
