Alt Codes Problem
 

A few of my co workers have been complaining that there alt codes haven't
been working. One of them swears that it has something to do with being
connected to the network here at work, that using alt codes for ASCII
characters at home won't work. I tried to explain that alt codes are always
present in Microsoft office. I haven't had a problem with them yet. Are
there certain presets in excel, word, or Microsoft office in general that
could "disable" alt codes?
