Removing @!!*& Storm Sash
This must be simple,but maybe I'm being simple.... Does anyone know how to remove the storm sashes from this type of window? It would seem that the rail on the side, holding the storm in place, would come out, but jiggle it as best I can, it doesn't, and it is preventing me from slipping the storm out.
I'm talking about the vertical white thing on the left, with the rounded top-right corner. I assume that needs to come out, for this procedure to happen.
Note: I'm not a complete nincompoop with windows. Why, I've likely removed sashes from maybe fifty windows, in my life. But this one has me stumped.
