Indesign Version 17.2.1
If I save my file as an Indesign file (INDD), the icon on my desktop shows Photoshop and not Indesign. As a result I can't open the file via double-click because then Photoshop opens and says "Der Vorgang konnte nicht ausgeführt werden, weil dieses Dokument nicht vom richtigen Typ ist". So I have to open it via right click, open with Indesign. That's a little bit annoying.
