Opus 9: no collapse to title bar?

The button in previous versions to collapse Opus to the window title bar appears to be gone in this version.

Is this the case? If not, how can I get this back?

Thanks for the new version, just upgraded ver. 8, and am still getting familiar with the changes.

It's called "zoom"


Hm, that option is checked, but I don't see the zoom button....

Are you on Vista? There are no zoom or pin buttons in the titlebar on Vista since it's no longer possible to draw into the titlebar.
