But consistent behaviour has it's charme as well: it's the principle of least surprise (POLS) - see http://en.wikipedia.org/wiki/Principle_of_least_surprise As mentioned before, I'd rather have a clear restriction that is consistent on all systems, instead of some "works for me" implementation on a few systems that will break under just slightly modified usage modes.
