Not an emergency bug fix, I just got on a roll and there was no point waiting longer before putting this up (don’t get used to daily releases).
Added storing and loading of a default font to the settings file, and a few fixes.
Changes in this version:
Added default font to the variables
Added reading and writing of the default font to the xml
Added pinvoke function to fix problem with some variable width fonts being identified as fixed width
Fixed minimum size of valid characters dialog when the font size changes
Added handling for System.Argument exception raised on some fonts
