@FED27 Looks like "Central Widget" is disabled. Do a right-click somewhere and select "Central Widget" in the context menu.

I have the same problem with exactly the same picture.
But I could not find the "Central Widget" anywhere. I went through all options/icons/menus...:-(
I am in Creator 5.0.1.
Will be really happy and thankful for the help.
