VST Connections window keeps popping up

A quick (probably very simple) question: As of today, every time I close a Cubase project, the VST Connections window appears. I’ve looked through key commands, etc., to see if I inadvertently keyed this in – no luck. How do I undo it? Thanks.

I have no idea but have the same problem: since this week when I used the media bay it opens every time I start a project - doesnt matter if it’s a new or old one…
It kind of annoying!
