It seems you have a corrupt stack.  The 2nd background exists (in some
wierd sense of the word) but without a card!  This is not good,
obviously, but I do not know of a good fix.  Bad media?  We need a
better solution to such problems, and actually someone is working on a
stack recovery tool.  In the meantime, get a copy of the Stack Detective
to look at what's going on, or you can also use Fedit to at least see
your info.  If the stack is reasonably small, BinHex it and send it to
me; perhaps we can figure out what went wrong.

	Usually you can figure this out from context.  If you just
copied a button, then you can count on it saying Paste Button rather
than Paste Text.

When you lock the screen you are freezing it, so any visual effects done
are NOT shown.  If you want to see the visual effect, you must do an
unlock screen or equivalent, such as:

lock screen
... stuff ...
unlock screen with dissolve

or in the old world of pre HC 1.2,

set lockScreen to true
... stuff ...
visual effect dissolve
set lockScreen to false

More into on this is found in the 1.2 Release Notes stack, which is full
of great ways of using the unlock screen stuff.
