I just received a box.com account from my school and, since Box Sync does not exist for Linux, I instead tried using the WebDAV service box.com offers.

I tried the Nautilus:File->Connect to Server... way. The connection works; I can access the files on the Box server.

However, from the moment I connect to the server, Nautilus takes ages to process any user input, both in and out of the WebDAV connection. As soon as I disconnect from the WebDAV server, it's working again.

Any ideas on how to fix this?
