For those of you unfamiliar with the "before" status (photos are truncated, click on them for full view) ....
The old windows, which were single-pane, and which wouldn't close properly and leaked heat in the winter and air conditioning in the summer. We've since determined that they didn't close properly because they were under so much pressure.
The new windows installed with proper headers and support studs underneath.
Notice how the 40-year-old (dark) stud is bowing to the right from supporting too much weight by itself.
Ross's solution for one of the windows on the South (porch) side wall which was to be replaced with a smaller window and had little-to-no support to begin with. Pardon the clutter beyond the window opening ... this is what our porch looks like while we store our kitchen contents on the pool table out there!

The living room with raw drywall installed.
Drywall, taped and mudded.
The state of affairs during priming.
Can you say ... nearly finished? We still have to do crown moulding, A/C vents, and re-installation of the ceiling fan, but I. am. thrilled!!!!!
