Hi, I have a Treo700wx on Sprint. It's worked fine for quite awhile, but has now stopped syncing sub-folders for my inbox. When I go to "Manage Folders" and check a subfolder and press OK, then go back and check the folders, the check box didn't hold. I've tried syncing before checking to see if it held, but that didn't work. I've tried lots of other things and finally resorted to a hard reset.

That has not fixed the problem. I tried creating a new subfolder on the device (via Manage Folders), and that folder will sync, but I still can't check any of the other subfolders.

Any advice on this problem would be very much appreciated.
