Accelerators - odd behavior

What is very interesting about this is that I can't duplicate it with the
"+" character.
I've added all of the following to the scene accelerators and it still only
fires my "plus" action once for each press.

KeyCombination cmdPlus = new KeyCodeCombination(KeyCode.PLUS,
KeyCombination cmdAdd = new KeyCodeCombination(KeyCode.ADD,
KeyCombination cmdPlusAsShiftEquals = new
KeyCodeCombination(KeyCode.EQUALS, KeyCombination.CONTROL_DOWN,
KeyCombination cmdPlusFromCharacter = new KeyCharacterCombination("+",

This is weird.
