Has anyone had a good GMail experience on Pocket PC?  I’ve got it set up and working with the default mail client in Windows Mobile 5.  Send and receive work fine, but the weird thing is that as soon as you open a message in WM5 Mail – the message disappears from the list of email.

This is not how it works with other “standard” POP3 mail accounts, why does GMail behave differently?  One thing I have not done yet is to search out for a GMail PPC client.  Has anyone use one?  How do you work with GMail on your PPC?
