Screen attributes use real screen not player screen - bug?

When I build and run the Networking demo - everything works fine. But when I try to run it in the Unity editor, it starts fine, reports no errors, but does not display the window. It took me a long time to figure out that this is because the window is being created outside of the player - using my monitor resolution instead of the player resolution. It does this with any windows I create. When played as an app, it works fine, even though the player screen is much smaller than the monitor screen.

There is probably some simple setting I need to change someplace so the games plays correctly in my editor.

Help please. Not liking the idea of having to spawn every window on the left side of the game so I can see it in the editor.
