Thank you SO much!! Your solution (2/13/07, 04:32:53) was exactly what I needed!! I, also, inadvertently deleted the symbol option from the insert menu. I saw the mouse pointer had changed to a big minus (and a plus) sign, but had no idea what that meant. It disappeared after I clicked the symbol option, but little did I know I had deleted the symbol option as well!
I am grateful for your clear explanation of the problem, as well as the solution!
