Zen shows multiple windows when using Macbook's Mission Control

[u/Mitsunami]

Hi all,

I have multiple tabs in Zen. Whenever I swipe with three fingers up (I believe that's what Mission Control means), it always shows several windows of other tabs active besides the one I am currently on. For example, as I am typing this post, if I swipe up, it also shows that 2-3 other windows showing different tabs are also available. I want to just have one window when this happens and not have the clutter of other tabs. I thought this was because the tabs are active and not sleeping, so I tried to close them, but the tab window still remains when I swipe up.

Is this something that's changeable in the Settings page? Thanks in advance for any help!
