Animation pane won't close, Network Pane won't close

When I am done editing an Animation, and click on the right hand arrow to close the pane, the option “close” in greyed out. Also noticed that the Network editor pane also cannot be closed.
Also the keyboard shortcut Alt-z doesn’t work on the animation editor pane

I was able to get out it by selecting the single pane preset layout.

I only notice this when editing the Animation comp, other split panes and options work fine

Try still clicking the greyed out button, it probably still works. There has been a bug for a while that causes the close button to be incorrectly greyed out, but it should still close that pane when you click on it.

Ha! wow I’m so gullible I didn’t even try clicking on the greyed out text! Yes that worked.

I also noticed that if I make it a floating pane I can close it that way too.
