ZDoom

When a user is playing full screen and attempts to alt-tab to their desktop, their mouse cursor gets anchored to a single position and can't be moved properly. For some people, it gets stuck in the center of the screen, while mine specifically gets stuck in the upper left corner. This seems to consistently happen with in_mouse 1 and it happens in G/ZDoom as well as Zandronum.

Here is a Zandro Ticket with some other details regarding the issue: https://zandronum.com/tracker/view.php?id=1618

I fix it by going into Mouse options and switching "Enable mouse in menus" on and off. Until there's a permanent fix, you can use that one.

Yeah that appears to be a work around. It seems this setting for the mouse uses Win32 API. Is it a shot in the dark this gets fixed?

Confirmed to be happening in Zandronum and G/Zdoom, even in recent versions.

The real question should be: Do we really NEED this mode anymore? The only system requiring it is Windows NT4 which is totally obsolete and unsupported by now.
This is not the only issue with in_mouse 1 so I am tempted to just remove this mode and pretend it never existed.

I think that's the most prudent thing to do. Leave the other modes, obviously, just remove the API version.

I was asking because some people obviously use it, otherwise these report wouldn't have been made. I need a bit more info before deciding to remove it.

If you're talking about the whole existence of menu cursor, I think the only useful place ever would be with the new ZScript menus where up/down isn't really a viable option anymore. In case of ListMenu, I mean.

No, this relates to how ZDoom handles mouse input for freelook/movement/etc.
