I absolutely HATE this horrid, ancient version of Word! Things are either in a different place, or not there at all!
I have just spent a happy few minutes with a narrow black felt tip and a ruler, well, if I'm honest not exactly a ruler, rather the cardboard from the back of a paper pad
and I can just about see the lines through a plain piece on top.
I have also discovered that we are completely out of "office" type envelopes, so will need to buy a pack tomorrow.
