One more thing to note about unplaced BGs - they and their contents are
not in the message path. So any hidden handlers in there won't respond
to normal message-passing. I haven't tried "dispatch" or "send" to them.

Thanks Phil.
As mentioned, I haven't really played with backgrounds very much so this
may be a stupid question but why would you want to have a background
that
doesn't appear on any card? I can see that might happen
inadvertently when
backgrounds get deleted but is there a practical use for unplaced
backgrounds?
One excellent use is for storage. All referenced controls can go there
without taking up room on any card. In fact, when you import a
HyperCard stack, all the icon images are put into an unplaced
background automatically as part of the process.
