When I assign the right option key as the forward delete, and then hibernate my laptop by closing the lid, when it reaches full hibernation and I return (open lid), the key remapping stops and nothing I do inside the DoubleCommand control panel fixes it.
This problem only occurs on Mavericks. I did a fresh re-install of DC on it, using the latest download from SourceForge. This problem never occurred on Snow Leopard.
Version DoubleCommand-1.7.dmg
