Notes on the Simulators: Notes on the Simulators:
The simulators are designed to be run at a screen resolution of 600x800 or better. If your screen is set for old-fashioned VGA resolution (480x640) you'll have to scroll a bit to see the whole thing.
M The older Macintosh Java Virtual machines (which run these "applets" in Mac Browsers) don't seem to support threads (multiple simultaneous processes) well. The result is that pressing buttons while the simulators are running causes the whole machine to lock up. I have heard, however, that recent Macintosh browsers have overcome this problem, but be warned.
