Joe -

In Word, you can choose whether to use curly quotes or straight ones. While theoretically the curly ones shouldn't break a post if they're just in text, they're not recognized in places where quotes are called for in html code and it's recommended that you not use them anywhere in html-ish situations lest they creep in where they aren't appropriate.

If you set your Word to NOT USE curly quotes, and then replace " with " all the curly ones should disappear and be replaced by straight ones. You should also, with the same setting, replace ' with ' to get rid of curly apostrophes for consistency.

The setting in Word used to be at Tools | AutoReplace but nobody knows where they put it in Word 2007. I found it once and turned off the curlies.

Okay - after a ten minute search:

In Word 2007 click the cow splat.

At the bottom of the drop-down click "Word Options."

Since you're wanting to change what Word does as you type, obviously you want to click "Proofing." (Silly me, I'd always done the proofing after I was done typing, but Mickey knows better.)

Near the top, you'll find "Autocorrect Options" and when you click there there's a section "Autocorrect as you type" where you can UNCHECK the "straight quotes with smart quotes."

(Five clicks in the new Word is lots better than three in the old ones.)
