I tried using the preferences to switch my font size from Monaco 10 to Monaco 12 or 14 and I got bigger text but it was all smooshed together like it was still using the character spacing for 10.
Is there any larger font that will work? The tiny font is messing with my eyes :-(. I tried Monaco, Courier and Optima, and they all did the same (unreadable) thing when increased to a readable size. (Well, Optima actually gave me text that looked in an entirely different language - go figure.)
