How to change the font size.

[melissa]

Hello,

I have wrongly changed the font size  to 8 & types of font  , thought it will 
change the size of font in reports so i can have a few pages print out of 
report  . But later i found that the font size changed in Accounts Register 
box which is very small for me to read.

But now i forget where the hell i went to changed the font size . now i dont 
know how to change it back. 

Pls tell me.  
Regards
Melissa.
