It's not the intended behavior, but controlling the hosts is the most challenging part of BAM!.
I did a quick fix, but it's not easy to concentrate this early in the morning with such little time.
And now all we can do is wait for the next one (and when it works, we'll probably never see a post "BAM! left all my projects on my host!"

.
Regrettably, here's the next one!
About a week ago I attached my first hosts without any problem. I have just attached 2 more and was horrified to see all the projects detached. Fortunately I tend to say 'bummer about the lost work', but I know some crunchers would be a bit more peeved than that. ); Also, these were my 2 weakest hosts, with only a few projects.
May I suggest that warnings to this possibilty are placed somewhere appropriate and prominent?
I have 2 more hosts which are not attached. I'll wait till you think you've solved it before trying them, and will let you know what happens. (oh wait, you already thought you had solved it!

)
Perhaps you need to try a slow fix this time

Maybe it's relevant that both of these hosts are Win98 - too weak for XP.
Oh, BTW, I love the live preview here!
