Well after alot of blood, sweat, and tears and many swear words, I finally got the 2 screens back into the window frames.
Working in the middle part of the window frame, I used a 3" wide putty knife, to act as a lever between the window frame and the screen frame, to push the screen toward the side that had the spring clip.
No amount of force would move it enough to clear the window frame, so I got a block of wood and placed it next to the putty knife, on the screen frame. Next I got my favorite persuader....a hammer...and while I was still applying pressure on the putty knife toward the center....I gave the wood several good, firm whacks with the hammer. Success, at last!!!
Now to prevent my new dog from getting at the screens and curtains again, I have to come up with an idea of what I can put under the windows to prevent her from getting near them.
Ever notice how one solution leads to another problem?
