Question 1:

I want to change my default font from MS Sans Serif to Arial.  
Using Format, Style, Define, Normal, Font, etc...OK seems to save 
a new default with a specific file, but not change the PROGRAM default 
Normal style.  Am I doing something wrong? Can the program default font be 
changed?

Question 2:

The problem that led to this was that printed file name 
headers with the MS Sans Serif font were dropping letters; 
CHOOCHOO.XLS would print (on an HPIIP+) as C___C___.XLS.  Arial prints fine.  Any ideas what's going on here ?
 
Thanks
