RE: MIA, Ask an Expert: arrow keys

Hi,

These are the ASCII values for a Windows computer. Are you running
MicroWorlds on Windows or Mac? On a Mac, the ASCII values would be 30, 29,
31, 28. The two sets have nothing in common (if they had ONE common value, I
would guess that you are looking at a "platform" issue, but that's not the
case).

Note: I see that your "forever" instruction is quite long... You should
consider programming the color detection in backpacks or on the page
(right-click on the color) instead, in order to gain some speed.
