a mac user cannot use the ctrl key (ctrl+left-click == right-click). Most games I've seen allow use of the 'option' key instead, but I have no idea how that would be implemented. Also, as others have stated a "sell all" button would be wonderful.
Very good game, very addictive! but, at least in version 1.50K, I've got an elevator beam right in the refueling/repair spot - so I no longer can on this planet, and have therefore also wasted a teleport pad - frustrating.
