I configured a toolbar at work today. I took the USB home and launched LBC from the USB at home. When I did that, the "Configure Now" dialog came up, so that was not right. Then, when i went in to configure, the proper FILE <name> toolbar was showing, but there was no "+" next to it. Meaning, the only thing in the tree was the FILE name. So I closed it, reopened it with from the USB, and everything showed up there fine.
Anyway, switching computers seems to a little klunky, at least on this first try of mine. It wasn't seamless.
