I have a broken pane in the storm window, one of those aluminum frame things that slides up and down in multiple channels.
Looks like a bb gun hole, then the whole glass pane cracked. But it could also be a stone thrown from a lawnmower, I guess.
Anyway, I got the broken one out of the window. But i can't see how to get the glass out of the frame. I've replaced a zillion glass panes in wood frame windows, with the glaziers points and putty approach, and done a few screens with the rubber strip and spline tool. But this one doesn't come apart in any obvious way.
What do I try next?
