Cannot close Project CSS window

1

I can open the Project CSS file from the Project menu but I cannot close it.
What’s the secret?

2

Close the tab for it. It will be in the tab bar across the top of the Code Window.

3

The only way to close the tab for it is to click on another code window tab.
Why not just put a Close X beside it like all the other code windows.

Okay, I see. It opens and closes at the same time as when you click on Project Properties and Global Code. That’s weird.
