WebDAV and Vista/Win 7

G2 works well, I can connect with WebDAV using the DataFreeway client, but Vista and Windows 7 cannot connect with their native WebDAV clients. Apparently the fix released by MS works only on 32 Bit versions of Vista (if that, I don't have a 32 bit version of Vista) and not at all on Windows 7.

Is anyone aware of anything different? Is there a fix out there I don't know about for Vista and Win 7? If not is there a better client to use than DataFreeway (its not so much bad as quirky and odd)?
