Hello, I wanted to report some funny behavior that I observed after starting a new project. I noticed that after importing a shift list via formatconverter and in that process assigning that new shift list to a number of spectra, those spectra don't fully reflect the new shift list. It shows up in the experiment list, but not in an existing window showing those spectra: when I select a picked peak it does not show the available assignments. I tested whether this is fixed when I generate a new window by cloning the existing one but that behaves even worse: the already picked peak marker(s) don't show up and I am unable to pick new peaks in this spectrum. During all this there are no error message on the command line, by the way. Note that if I save the project and restart it all behaves fine again. Patrick
