Carrol,
what is your mail program? I assume you are using Windows (if you are on a Mac, Ctrl-scroll will magnify your screen). If you are using Windows XP see:

Also, what about the speech-to-text program that Michael P uses which seems to do a good job, occasionally giving us some interesting new words... though I think a recent one from you is my favourite: thoughrt = thought yoghurt -- cultured thought informed by sweet sentimentality! ;-)
