Duh

Encountered a computer problem last night that I spent hours trying to fix, unsuccessfully. USB ports on my old computer stopped responding. Finally found a suggestion on the net, tried it and it worked. The solution was: unplug the computer from the wall and plug it back in! (I keep forgetting that rebooting is NOT the same thing.) So I'm back to full speed. Whew. Spent maybe 3 or 4 stressful hours before doing this. Duh.
