I think I've gotten to the solid wall mode a couple of times, briefly, but I don't remember it well. Smile.
What I do remember is the portion of brain malfunction where I put the screw gun tip thorough my finger leaving a bloody trail. More than once. I then took a vacation, as it was clearly needed (and that worked). I'm currently quite clear on this subject; when I begin to think that a cruise on board ship sounds good, I should down tools and take a rest.
