Mathtype, Word '08, Pages '09, etc.

[MFrantz]

I've been working on a math book in Word '08 with literally hundreds of Mathtype equations. My problem: finding a way to change the font and font size in large numbers of equations in some time-saving way.

I used to be able to do this in Word '04, and I may be able to do it in Word '11 if I shell out the money.

And this is driving me crazy: sometimes when I double-click on an equation, it changes the format to the last one defined, which would give a fairly quick method: but most times it doesn't, and I can't figure out what makes the difference.

Does anybody have a suggestion? I have Pages '09- would that make a difference? Aaaergh.
