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?
