In article <6561@cbmvax.UUCP> daveh@cbmvax.UUCP (Dave Haynie) remarks:
	[Essentially that he uses fonts correctly in SetFont 2.5 so
	 that shouldn't be the cause. ]

Here is a word of warning for folks that use fonts in their programs other
than the ROM fonts. How you open a font is _very_ important. You should
always use the sequence :

	tf = OpenFont(&font_i_want);
	if (! tf) {
		tf = OpenDiskFont(&font_i_want);
		if (! tf) {
			WarnTheUser("Can't get your font.");
			optional_exit();
		}
	}

Many programs simply call OpenDiskFont() first which does not check the
in memory font lists and instead does just what it's name implies, opens
the font from disk. This is arguably a bug, however since using it in the 
above manner will cause it to work correctly, if you are using non-ROM 
fonts you should note this behaviour.

These opinions are my own and no one elses, but you knew that didn't you.
