I had the same experience as Vincent (see above). Before, the utility removed *all* instances of "Re" and "Fw". After reinstalling the software (after being told by the program that I needed to reinstall the runtime utility), the program now removes only cases where the "Re" and "Fw" are duplicated, but it leaves the original "Re" and "Fw" in place. I'm not sure if this was deliberate or unintended, but it is a pity.
