Hi, I have discovered an issue caused by a new change of behavior on the Folder Tab bar. The changelogs (13.13) are describing the change by: You can now drag folder tabs out of the tab bar to create new windows for them (like in a web browser), without having to drag them to the Windows desktop…

I confirm that it is fixed with the 13.13.1 (Beta) version. Thank you for your help!
