If you have a File Dialog open in an application, eg Photoshop, and use Alt+tab to switch to another app, Listary will show up as an open app.
Minor UI annoyance, not a major issue, but it would be nice if Listary didnt show up in the alt+tab view. It doesnt in the Win+tab view and i dont remember that it did in version 5.
Here are the instructions on how to disable Listary and Photoshop integration (which can be applied similarly to other software).
This will temporarily resolve your issue, however it will disable Listary’s functionality in the File Dialog.
Hope that there will be a more reasonable solution for your case in the future!
