It will. Please read the design page :-) My point is that there is a 
small restriction on drag-select, which is that you can only do it in an 
additive fashion. If you wish to have the selection be only the things 
you drag-select, then you need to clear any existing selection before 
you do the drag-select.

I am only attempting to respond to a problem which participants on this 
list tell me is real.

I suppose there is no reason why unmodified drag, starting in an empty 
area, should not do a (resetting) drag-select. But people seem to think 
that this should not be the only method.
