We are proposing a window that contains checkboxed items; we wish to make it
illegal to deselect all items in that window.  The current solution our group
has come up with is to "beep" at the user (and put up an explanitory dialog)
when s/he tries to deselect the last checkbox.

Problem: I don't like beeping at users.  I would much rather somehow visually
show that the last checkbox can't be deselected.  Greying out the last checkbox
would solve this, except that greyed,selected items are apparently illegal 
(i.e. against the Apple HIF guidelines).  Do any of you out there have any
other solutions?

Thanks,

Mark
