That did it! What an easy work around now that I know how to do it, now I dont need that addon really. Thanks so much! By the way, if I do that with a 10gb Mbox file, will that cause thunderbird to freeze/crash each time I start it? Or how big of an mbox file can it handle? I assume each time you open thunderbird, it manually loads that file from the computer.
