I think they're wrong: CloseIEx website says "license: shareware (fully
functional) (for 30 days trial).
You can check it yourself: http://www.geocities.com/closeiex/
IMHO they just see the update and not the license modify.
I have 2.6.05 (registerware, but still free) in rareware section of my Mole
Zone (url in signature).
