Sorry for writing here, I do not know what is Alpha Channel, but I have a problem a certain png files too. Some were broken(half downloaded), but another seems perfectly fine(and MS Paint opens all these files). XnView just refuse to open such files and shows empty gray screen with error(with default settings).
So the solution is: Options>Formats>Read - check "ignore read errors"

Hope this will help someone eventually too :idea:

Finally found it! Not in browser mode! Everything works, but the settings are not saved - each new file has to be re-enabled. How to set the default?

Yes, but it doesn't affect the display in full screen. I don't know who needs to see a png without an alpha channel by default. How do I enable it permanently?

By default it's on, in browser preview you have no alpha used?

Do you talk about settings in preview of browser or edit mode?

I did a lot of manipulations as an experiment, then it is displayed in edit mode at the same time in full-screen mode, in general, somehow I managed to install it, closed the application-opened it and it seems that the alpha was saved
