I may not be the best person to try to answer this, since I'm waiting quite impatiently for my Axim to arrive. However, I found something that might be worth trying. I'm attaching the most recent windows drivers for the Axim USB sync from Dell's site. Based on your description, I suspect this might clear things up. And if it doesn't, well you can still feel good knowing you've got updated software, huh?!
Oops! It won't let me attach this type of file so I'll have just post a link
R55367.EXE from support.dell.com
Best of luck!
(By the way, a friend and I both ordered our Axims on 1/15, but the order didn't seem to process until the 20th... I wasn't terribly worried because I figure there were a LOT of people trying to get in before the rebate deadline. I was originally estimated shipment for the 4th, but when the order was confirmed I got dates of 2/14-18 for delivery. Just got the tracking number and my friend's ship date has been moved up to tomorrow, the 7th...but for some unknown reason mine isn't trackable yet!! This isn't a complaint at all, I'm just really really really excited to get my new toy and I don't wanna wait any longer! Waaah! ;)
