When trying to load or save files, WISO Steuersparbuch 2021 opens a wine file
dialog. In this dialog, I can navigate directories and select files as usual,
but clicking on the open or save button does nothing. However, the button is
visually pushed in on click.

System information:
* Newly installed Ubuntu 20.10 64bit, Intel GPU
* wine staging 6.5 from winehq PPA
* clean 32bit wineprefix
* winetricks vcrun2019, Set msvcp140_1 to Native,Builtin (this is required to
install and launch the application)
