hmm... there is only one molecular system in the project, thus linking
to the wrong one is not the problem. However, I find myself in the
interesting situation that I can invoke "Show on structure" from the
PeakListEditor for some of my spectra where I cannot invoke this from
the AsignmentDialogue for the very same peak (restarting doesn't resolve
this situation). So my problem is clearly not an issue of an unconnected
peaklist...
What about ProjectLinkGraph much in the spirit of the AssignmentGraph
that shows all major objects of a project and the existing Links between
them with some buttons that allow to create the missing Links? ... just
a thought
