It's not a problem at all, but it's not what the "Enable Frame Undeletion" 
menu item was meant to do.  It was meant to tell users that it is 
necessary to add somethig their init files to enable that feature.

I attach three possible solutions, in order of personal preference:

1. The original design: the "Enable Frame Undeletion" item disappears once 
it has been used, and is replaced by the "Undelete Frame" item.  Users 
have to use M-x undelete-frame-mode to turn that feature off, and it is 
turned on only during the current session.

2. The only menu item is "Undelete Frame", but it has a "Undelete-Frame 
mode is disabled" tooltip when undelete-frame-mode is off, and a "Undelete 
the most recently deleted frame" tooltip when it is on.

3. The "Enable Frame Undeletion" item disappears, and a "Disable Frame 
Undeletion" item is added after the "Undelete Frame" item.  It uses one or 
two menu items, but a least it doesn't shift the whole File menu to the 
right because of a checkbox.
