Audio Comps, Which tool needed to select comp area in audio region Options

[iDavid]

The manual, and the David Lahmani book say the pointer tool, by click-dragging is used in Arrange to select the area in an audio file to be comped. it doesn't work in my LE 8.0.2-the region just moves left or right when click-dragged with the pointer [that is the arrow-right?] has any one seen this before, does any one have a work around other than split into regions and copy/paste? any help will be much appreciated.
