hi

check if you have overflow to this lines or the group...maybe stacks there.
you can check it by puting this lines out of the group and and check them one by one by calling them when you puting them again inside in the group.
so you can see witch line makes you the problem.

If this is not a problem try an other NDDI 2 board...
