When you backspace through a linked clue and land on a shared end-point (for eg, 1ac ends where 3dn begins, and 1ac is linked to 3dn), you cannot backspace further unless you click to toggle the direction. I had not implemented backspacing across linked clues, which seems like an OK thing in general, except for this "shared end-point" situation.
