thanks ... is the situation that I described abnormal? ... for instance, which format does your cs6 use?
i've never seen that before.
i only see the fla name, not the path/name (unless i hover over the fla name, then the path/name is displayed in full with no tilde).
it might be an os setting if resetting preferences doesn't reset it.
