Changing Default font in notes under General tab

I have the same problem. Somehow -- I have set the default font for the text area to Berlin Sans FB Demi size 10 bold which is hard to read. I want to change it back to something like Arial.

I fixed mine.

Tools | Options | Mail Format tab
Under the Message format section, clear the checkbox "Use Microsoft Word...". That un-greys Stationery and Fonts.
Under Stationery and Fonts, click Fonts.
When Composing a Message, Click Choose Font. Set your disired font | OK.
Check "Use Microsoft Word" if desired. | OK.

Charles,
Thanks!! I would have never guessed since there is no mention of Contact fonts under that heading.... I appreciate your help.
