Correct process to switch to a new layout

I'm having a little problem switching from one layout to another. Visually the new layout appears but I can't interact with it. I deleted the class that has the prior layout and is derived from wraps::BaseLayout. The destructor is called.

Any ideas why I can't interact with the new screen? Is there anything special I need to do to clean up and remove a prior screen?

Adding a layer tag to one widget other than the canvas has seemed to help.
