Zeno's Window

The painters are hard at work on their scraping and painting, and pictures will be forthcoming. So far, we have hit two bumps in the road. The first is that they started to paint some of the trim the wrong shade of white (and yes, like the Box o' Vinegars, it feels way too grownup to be spending lots of energy differentiating shades of white) but luckily we caught this before it went too far and the painters were very gracious about re-doing that work.

The other problem seems like it may be harder to overcome. You see, we have this window in our dining room. And at some point shortly after we moved in we noticed there was a problem with this window and that the top part of the window got pushed down behind the bottom part. So far the only way that this has negatively impacted us is that on the top there was only a storm window between us and the outside which is not exactly the best insulation, but we dealt with this in a very ad hoc manner with many sheets of plastic, all of which were nicely hidden by our curtain. But now we need to remove the storm window for the painters. And we cannot do this because there are not one but two big pieces of glass between us and the little buttons we need to push to remove the storm window. And neither of these parts of the window move because (according to the painter) they are jammed in too tightly with the storm window and the screen. And even after removing some of the molding to try to access the window, we don't see a way to get it out. Oh, and did I mention that the ropes have all broken, too? Hmm.

Anyone know of any magic ways to remove windows?
