Beware - newer versions of DD 3.2.x can corrupt dialogue files that were created in older versions of this program!
I believe there's also an issue with duplicating messages, as that can lead to broken links (though only in the export, so you can't see them inside the editor). I'd strongly advise any one using this program to avoid duplicating message boxes and instead spawning a fresh one each time.
Radmatt - Can you please make earlier versions of this program available? I'm 70,000 words in on a three year project and opening old files in 3.2.4 more often than not breaks things :(
