The entire left hand side of Mail has disappeared. It is just pale blue. All of the file headings and their contents have mysteriously disappeared into the ether. Can anybody tell me what has happened and how to remedy this please.
Mailbox was set to Lucida Grande ??????? Message font was set to Helvetica????? The only thing that was unusual before this problem happened was that I wiped the keyboard with a soft cloth - if that caused it then I would be flabberghasted!!! What do you think?
Sorry but I did not notice the "look for duplicates" bit of your message. I found that there was a duplication of Hiragino - I deleted it. I expect that you can tell that I am no expert so I hope I have done the right thing.
The font stays the same no matter what I do. Can you explain what you mean as if you were talking to a complete novice please ? Could you go through it step by step as I am not sure I am doing what you are asking me to do properly.
The Text has to be highlighted when selecting a different font, use CMD+a, or the Edit menu item after placing the cursor in the text... or you can Drag select the text you want then change the Font or siz, color, etc.
