Martin,
I think that you are confused, there is no limitation on
the actual number of windows that are created which means
that you can open as many new windows until your system
runs out of resources ... regardless of what the menu
item says or does.
The same thing happens on QNX if I open up 50+ windows on
my home machine, but at that point the fact that we don't
actually check the return value on a number of created objects
when they fail is due to give you a segfault.
Such is life.
