D'oh! It just had to be one of my own posts, didn't it? Thanks for pointing out my failing memory!
I'm with you there. Last night I was heating leftovers in the nuker and couldn't understand why it wasn't starting. I kept trying different times and all it did was beep the 'no' beep. My wife came over, closed the door of the nuker and hit the start button. She's so sweet in that she said nothing. But she's still smirking this morning.
