I didn't reply to this thread earlier because I figured one of the usual 
experts would pick it up and run with it, but it appears not.  By reading 
Selwyn's answer, I think he knows how to do this but decided to vent about 
the method rather than explain it.

In the Option Inspector is an option called ScriptSizeMultipliers.  This, 
combined with the ScriptMinSize, determines sizing for fractions and 
scripts (sorry, Selwyn).  The easiest way to do what Murray and Sabit want 
is to set the ScriptSizeMultipliers option to 1.  This could be set at the 
notebook or global level, as you feel appropriate, or wrapped individually 
around fractions if you don't want sub/superscripts to pick up the option 

To answer Sabit's second question, select the bracket of the cell you'd 
like to change, and use the Option Inspector to set the SingleLetterItalics 
option to False at the selection scope.
