I completely agree with you that this looks rather strange, however this is a real screenshot, and not a collage that I made in Photoshop.
This error occurs in different places.
For example, in steps:
1. I launch the player 2. I click the equalizer icon in the bottom pane to open the "Equalizer and DSP" settings window. 3. In this window I click on any item and get an error message.
Made a screenshot in another version with the English language interface.
I also do not understand what kind of "unselected files" in question, but the fact is that such an error occurs. I did not draw this window.
As I already wrote, it began with the 3rd version of your wonderful program. During this time, I changed 2 computers and, as the new version of MusicBee comes out, I install and try it. Sometimes an error may not immediately appear, but sooner or later it occurs.
Therefore, I use version 2.5. Sorry if you are upset. I nevertheless decided to post this message in order to make your program even better ...
Thank you very much.
