I’ve attempted to reproduce your issue, but when I middle-clicked on the tabs, it did not move my Unreal Window to my primary monitor. Does this happen in every project, or just your current project? Do you have any unusual settings that could potentially be causing this issue? Is there any more information you could provide that may help me in trying to reproduce your issue? Thank you.
Thanks for that post, I would have never found out that it was my Display Fusion doing that. I’m not sure why that shorcut is enabled, it’s pretty annoying and not something I would expect.
