I'm using console applications or at worst, the
generic Windows application. In both cases, it doesn't
work. Print crashes my program, usually right at the
print statement (The message never makes it to the
console or stderr.txt file.)

I'm still using Lua 4 too. Can you tell me more about
_ALERT? I don't know about it, and I don't remember
seeing it in any of the Lua documentation I have.


Thanks,
