From: Elvis Dieguez <elvisum(a)uclink.berkeley.edu&gt; Date: Tue, 16 Oct 2001 17:56:09 -0700 Whenever I try to change the fonts I get the error message: Wrong type argument: number-char-or-makerker-p, nil Any way to fix this? Elvis Dieguez I've saw the same error, but forgot about it... You can get this error by clicking Options -> Font -> courier new (for example). The error occurs in font-menu-set-font when doing the default font.
