Xcode 4 breakpoint switches to "assistant view"

How to prevent switching from "standard开发者_运维问答 view" to "editor view" in Xcode 4 when I'm debugging and hitting a breakpoint?

I want to remain in editor view.

Xcode Menu, Preferences, Behaviors Tab

The behaviors panels controls what windows show and which actions to take as different activities happen.

Under Run Starts there's different options to control which windows show.

Hope that helps.
