Dick, Thanks! I tried it out tonight and got consistent messages from the PC. You were correct about having to continually do message reads until I get something.

Hi John! I think there is not an urgent need for a clear-screen flag in a bunch of NXT screen functions.

The NXT-G firmware implementation for mailbox messaging is extremely funky. I don't think your code is working properly for this implementation. You need to be continuously calling "ReadMessage" and only check for "a message was found" error code. (...) (18 years ago, 14-Feb-07, to lugnet.robotics.nxt)
