I recently purchased a US Robotice Palm Pilot and learned the hard way of a problem. I'm not quite sure yet what the nature of the problem is, but one of the effects is that I lost my in-box in my mail reader. Somehow, the desktop software caused my hard disk to seem inaccessible to the newsreader, which promptly started a new in box. I did have a backup. However, my most recent backup was on September 26. So, if you sent me some e-mail since then, please resend it.
I now reboot my PC after I resynch the Palm Pilot (until I learn exactly what is going on). If my Ditto drive didn't require that my video driver is running standard VGA, I'd do backups more frequently.
Fortunately, this affected ONLY my in box. Messages filed to other folders were unaffected. That means I still have all my junk mail (well I could simply delete it, right?). I also still have all messages I manually filed somewhere, which, for the past month, unfortunately is only the automatically filed stuff, meaning one-on-one message are probably history.
