When my window-unit air conditioner revs its motor, my overhead light dims... then seriously brightens up when the AC slows down. It's annoying. Is there anything I can do? [more inside]

I have a table lamp that takes a three-way bulb. The lamp does not have a standard switch; rather, you adjust the intensity of the light and turn the lamp on or off by tapping the metal base one, two, or three times. Recently the lamp's bulb burned out and I replaced it with the same kind of three-way bulb that was in there before. But now tapping the base produces no effect - the lamp stays on its brightest setting and can only be turned on and off by plugging it in or unplugging it. What happened, and can it be fixed? I've only had this lamp for about six months, and it wasn't cheap. I've tried various different bulbs, but nothing seems to work.
