Hi Brian,

re:

This one is different from that and is the intended behavior.

When you set Options > View > Background color > Custom, what it means is "use this viewport background color globally instead of using the theme's color".

In v4 and earlier there was also a setting for setting the viewport background color (globally as well since there wasn't themes in v4). Since v4 and v5 are doing the same thing here they both use the same setting in moi.ini .

It's normal and intended that by default all versions of MoI share the same moi.ini file so they will all automatically pick up your customized settings for any changes from the default behavior.

If you like it's possible to set things up so that v4 and v5 will use different moi.ini files and so have independent settings. To do that modify the shortcut you use for launching MoI and pass a command line parameter to MoI.exe giving it the full path to a separate moi.ini file, it will then use that file for saving and loading settings. If you have any spaces in the path put "double quotes" around it.

Or another way you could do it is instead of setting the option to make the viewport background a specific color always ignoring themes (Background color: "Custom") you could leave it set to "By theme" and make a new theme to use and modify that new theme's background color.
