--- Comment #11 from Frank frank.heinz@gmx.de --- I've tried to create a debug trace. However, the program does not load the data anymore. I don't know what's going on but I don't think it makes much sense. Two observations: 1) The program always crashed when using a preview function like the "ELSTER" button 2) I've carried out the tax declaration on a windows machine and observed that the first thing the program does before transferring data is to call a preview function. Maybe that helps.
