SW Explorer 2007 and license usage

In the SW Explorer 2007 the first page of the help fileclearly states that SW Explorer "Does not require a license". Yetwhen I open SW Explorer it uses up one of our SW Office licenses. Ihave unchecked the PDMWorks Workgroup add in check box in theoptions but it still aquires a license. Whats up with that? SWExplorer 2006 doesn't do this.
