Stop auto capitalization after a foreign language punctuation mark in Pages

I use Pages '09 for both english & spanish articles i write. I'm noticing whenever i write in spanish & i have a question that's placed in the middle of my sentence, Pages '09 automatically capitalizes the first letter of the word that follows my question mark when grammatically, it doesn't have to. Does anyone know how to turn off that function?

Btw, Pages '08 never did that.
