@guy038 said: First, regarding the bug I mentioned in my two previous posts, I also detect it with native N++ and, for example, the Find Results panel : Thank you for that additional information. I had a suspicion this was a Notepad++ behavior not really related to the plugin. I have not been able to reproduce it. It is possible that it is dependent on some detail of your operating system or drivers. Since you can reproduce it without any plugin, I suggest adding it as a Notepad++ issue if you think it is worth further investigation. It could be that others will be able to reproduce it, perhaps including someone who can run Notepad++ under debug and close in on what is going wrong.

@smcclosr , The UAC for Admin credentials is always given when the Windows OS replies to Notepad++ that permission is denied for writing to a file. Unfortuntely, Windows can give that message even when it’s not really a permissions issue. As @mathlete2 says in this similar discussion from April, it might be that OneDrive hasn’t fully connected when you log in – so if OneDrive isn’t “awake” yet, then when Notepad++ tries to read or write from a OneDrive folder, Windows might report that as “permission denied”. And in December, @xomx mentioned in another discussion that Windows “Controlled folder access” can cause problems for Notepad++ and OneDrive. I suggest looking into the suggestions made in those two recent discussions, and see if either ends up being relevant to your issue.

@CJBlake1 , Rereading my original response, that came out harsher than I intended. I got interrupted with real life, and had decided to post as-is, before I had a chance to audit my post, so it was too “raw”. What I was really trying to say: I don’t think the specific version of Edge is really relevant to your issue. I am assuming that you used to have XML associated with Notepad++, and then suddenly it wasn’t anymore. Unfortunately, many applications (Edge included) have programmers who think that there software is the only one that matters, and that they should “take back” their favorite filetypes (like XML), regardless of decisions a user has already made. So I’m assuming that some recent update in either Edge itself, or in Windows in general, caused Windows to change (or reset) the default application for the XML filetype. There is nothing that Notepad++ can do to prevent the OS or an overeager application from hijacking the filetype. The best thing you can do in a situation like this is to use the OS tools to re-associate the filetype with the program you want. In Windows 11, the most reliable method for doing that seems to be using the Open With from the right-click menu: right click on an XML file, choose Open With, select Notepad++, and be sure to say, “always use this app from now on”.

@Italian-menu , Why in the world would you think your post helpful? “depending on what you’re using” – of course they are using Notepad++. This is a Notepad++ forum. If you cannot give a human-created Notepad++ -specific answer, don’t bother posting.
