--- Comment #7 from Frank frank.heinz@gmx.de --- That does not solve the issue. After updating to wine 6.6 and re-installing WISO (including its latest update), when invoking the "ELSTER" function which calls the external database, now the program freezes instead of crashing. It shows an empty window with no controls.
