Font not changing in interface builder

Hi I am new at using interface builder so please bear with me. I am trying to change the font in my viewcontroller.xib file. I can click on the font and highlight it then I open up the fonts window and select a font that is compatible with both ipad and iphone like chalkboard and select it and then it never changes when I click off it? The colors doesn't change either? Any help would be greatly appreciated. Snap to guides is not checked.

Thanks

Might have solved my own problem here:
Tools>Attributes Inspector ?

But I am now on a different machine. Anyone?

OK Back now and got into Attributes Inspector where I successfully changed color.The font changes and then when I clickl off of it it goes backto helvetica, crap! LiL help? Nothing like wasting a night away.
