I got this message that reads: "Crafty has cause an error in <unknown> Crafty
will now close.  If you continue to experience problems, try restarting your
computer"

That was just from pasting it in, not from the Analyze command.

But since you asked about it, I took a close look at the message and said
"that's the damn Windows, not Crafty!"  So instead of pasting it into the Dos
box, I pasted it into a file, and loaded it with "epdlrec", I always have to
look that thing up cause I never remember that command, and now it's analyzing
the position just fine.  Thanks.

It's not real thrilled with it though, it's not getting very far yet (but I am
using the browser too.
