narzoul: Ok, I managed to reproduce the issue now. The minimization must have been caused due to interference by some other app. I closed most other apps and now the game starts with >100% DPI scaling too. At 300% you indeed can't click the Apply button, presumably because the (invisible) window borders/caption become too large.

However, this issue is definitely fixed for me by the Might and Magic IX fullscreen fixes I linked from PCGamingWiki earlier. Are you sure you installed it correctly? It should show up in the list of apps where you can uninstall them, as "Might and Magic IX fullscreen fixes". Type "add or remove programs" in start menu search, open the result and search in the app list there. Also, make sure the executable file is called lithtech.exe. Maybe try launching the game directly with that.

nihility1008: Hello, I'm trying to get mm9 working right and I'm having some issues, I managed to fix the black screen at night/underwater with the zip file mentioned earlier in this post but after doing that I'm getting an odd mouse glitch, moving the cursor has a jerky movement kind of like having two mice plugged in and having two people controlling the cursor at the same time. I tried the full screen fix also mentioned earlier but it didn't fix the issue I'm having. Any ideas would be most welcome ty
