The zoom level does not change back to the standard setting when opening a
different project or system.
A fix has been checked into CVS.
Looking at bug 96 I now realize that bug 52 was not at all about the simulator.
That one has always reset the system back to the original zoom level. Bug 52 is
about the *editor* not resetting the zoom level when a new model is loaded.
I therefore reopen the bug.
A new fix has been checked into CVS.
