Emphasize this. While I - as a programmer - really appreciate the VMWare programmer's skills so they managed to fiddle buttons into toolbar icons I consider this an extremely silly idea. There is absolutely no benefit from this gimmick, the usual method to use the context (right mouse button) menu is sufficent, safe and self explainig. The way the buttons are now they are kind of a time wasting UI trap, and AFAIK there isn't a way to make them ask for confirmation either. Note: not everything what can technically be done shoud be done.
