Thanks, Steve. I remembered the breadcrumb at the top but forgot about that.
Can you use that technique to install onto a USB stick? It'd be useful to have Logos on-the-go without having to be constrained by Biblia. (Not that Biblia's not great, but it's not a patch on the full setup.)
I don't think Logos is runnable from a USB stick since it relies on registry settings, but I've never tried it myself so I'm not sure.
You could consider getting a Netbook and installing on that. See http://community.logos.com/forums/p/12048/94160.aspx.
