So I found the culprit!
First we did want to implement some user control. So I included the
security UI of the DSC module. In my changes it wandered into a sub VI
of the initilization process -- but as it activates the security
features of a front panel, I suppose it should be located on the block
diagram of the main VI! And that works. If I move it back to my main
VI, all is OK. (Well I'll remove it as we don't need this feature
anymore.)
So actually it was really the initilization code. And now I understand
too, why it worked in the development system. I suppose that the dev
system loads theses function and by that this VI doesn't have any
impact.
Thanks for all your help.
Cheers,
Carsten
