Unable to edit panel in simple editor

When I try to edit a panel when it looks like this:

It will instead wright in the Rhino command bar. However when I use the full “editor”, it works fine.

Is this a bug or have I accidently turned on something?

Hei Anders -

That’s a bug. When you restart Rhino, can you systematically reproduce that behavior? If so, please let us know the steps to do so.

Thank you. I will try to see if I can repeat it. It went away after restarting.
