This time Terry put the dough in the microwave with two cups of warm water and the yeast did its thing the way it was supposed to do it. (We had tried the "heat the oven and then turn it off" trick once. Didn't work.) It didn't hurt that the house was a toasty 68-70 degrees.
I may just have to start a batch of sourdough again.
Unfortunately, I have to wait until after she gets the Easter food blessed tomorrow at noon. (Unless I can realy, really fake sleep walking....)
