Fractional Dimensions not working, keeps changing back to decimal?

I can't get my dimensions (smart dimensions) to stayfractional, am I missing something?
They keep reverting back to decimal even when I go into units andchange them to fractional . What I really don't understand is somedimensions will stay fractional while others no matter what I do Ican't get them to show up in fractions at all? It's driving menuts. I'll have one that shows up example 27 15/32" while anothermay show up 24.867" I'm disgusted, what am I doing wrong?
Ideally I want to have a seperate drawing template for fractionalwork.
Any tips or suggestions please by all means I'm all ears.
Thanks in advance,
Brad
