David,
We started up the NXT ( we have version 1.0) fresh today, after a good
rest. and everything worked fine, it took the block plus several
more! We did discuss one common factor, this seems to happen after
the robot has been in use for maybe 2 or so hours with LOTS of programming or
changes to a program. Any thoughts?
The blocks are no longer on the program for me to attatch, the student took
them off when he could not get them to work. I did look at them and they
were simple move blocks, ports b and c, 75 % power, 2 rotations,
brake. The original block was done in degrees, they have learned how to
access the view window and push the robot manually to it's
desired stopping point and then key in the degrees on the move block.
Thanks,
Tracy

In
that case the obvious answer is out of memory error when downloading
but from what you are saying there is no such error and it appears to
download just fine. Therefore I think you are making a assumption
that
the block was not included. There may be physical
conditions where
they block does not appear to run.
Can you you attach
your program?
Also do you want to cc the listserv again since there are
a couple of
others that have chimed
in?

I was reading up on My blocks to see if that would help. I
