Hmm, thats strange. In my first release, I had it as M10tts instead of B10tts. It should be a B script so that it doesn't run concurrently with anything. If you happened to install the first version did you make sure to delete the M10tts before putting on the B10tts? Do you have any other M scripts running? I think that since my B script mounts the drives that other M scripts might be launched simultaneously to the B10tts script.

If you do have other M scripts, I think that since my B script mounts the file system you can rename your M scripts to a B script that is alphabetically after the B10tts script and it should work.
