OK, I deleted the applications and the driver. I downloaded the files off the ZUG forum and reinstalled. A few hiccups, but I got to the point where I was able to set the synchronization options. It still did not seem to respond when I clicked OK, but it saved my mappings. However, when I double click the Synchronize shortcut, nothing happens. If I click the Sync Start button on the Z, I get an error that says:
An error occured during the data communication:
Please remove the Zaurus from the Docking Station or Serial Cable and reconnect.
Please verify that the PC Link application settings on the Zaurus match the Zaurus Manager settings on the PC.
WTF. The Zaurus File Transfer application works fine and the Backup and Restore app communicates just fine, it just chokes on the Japanese bookmarks.
