Remember that the dictionary does not make a distinction for adjectives in regard to hyphenating. The dictionary gives the "direct adjective," right in front of the noun, form only. So if you look up "long-range," it is shown as hyphenated. This does not take into account that the RULE says that a predicate adjective is not hyphenated.
...I have long-range plans.
...My plans are long range.
...I have a full-time job.
...My job is full time.
Happy punctuating!
