I wondered why I had seen a post on Microsofts site for a new upload for Activesync, version 3.7.1 but when I checked my current version I saw this was the version I already had! The Pocket PC Thoughts descibes the bug fixes in this particulare version of ActiveSync 3.7.1, which includes a problem that I get - explorer shows an empty directory when you browse the Axim.
Why they didn't release it as 3.7.2 or 3.7.1a but it would have been handy.
