These are called detached processes.

An app can choose to show up in the switch list or not. This has nothing
to do with process type.

Yes. However, OS/2 supports the notion of hook DLLs which can intercept
keyboard and mouse input before the focus window gets a chance to process
the inputs.

Yes. Yes.

>Q4: Can a window be popped to the top of the display (so you can see it,
>i.e. "always on top") but _not_ receive "focus"?

Yes, sorta. The only way I know to do this is to take focus an pop up and
then return focus to the original app.

I wouldn't doubt that it's an old app that has not been enhanced in quite
a while.

Regards,

Steven
