Boomerang "stack" button latching

[David_Mitchell@HP-Australia-notes1.om.hp.com]

Some time back someone pointed out that the "stack" button on the Boomerang
needs to be held down when layering sounds in a loop.  I re-read an old
magazine review (written mid-96) of the Boomerang last night where this was
pointed out to the manufacturer as a failing of the unit.  The manufacturer
replied that they were considering implementing the "stack" feature via a
latched button - double click on the button enabled stacking, double click
again to disable - due to user feedback.  From the gist of the article, I
got the impression that this might be a software update only and not
involve a physical switch replacement.

Does anyone know if this feature has been implemented yet?  It seemed to be
the single major failing of the unit, according to the reviewer.
