I asked Colleen to swing by yesterday and help me remove the kitchen window (hers lifted out so easily) but would anyone be surprised that we ran into issues?  

After considerable time/effort I called in reinforcements (Ben, from across the street) but that didn't work either though he tried several different things.

So I called a glass place, figuring they could help me.  But when they heard that the frame wouldn't lift out (because the sink is in the way) they said I'd have to get a plumber to do that before they could fix the window.

Ah, the joys of home ownership.  

Where is General Services when I need them, Bana?
