Edit and Update Scenes is Grayed Out

The screenshot shows a scene I was trying to edit. When I tried to click on OK, it was grayed out. The same thing is happening when I try to update a scene. Earlier it was working, but then I canceled a scene that I wanted to change. After the cancel is when the graying out occured.

So, I saved and closed all programs. Then, I restarted the laptop. After opening up SketchUp again everything worked fine. Problem solved. When in doubt, reboot.
