Has 4.17 bugged my other versions?

Hi,
Since installing and starting a project on 4.17, when I go back into other projects on older versions, my mouse doesn’t seem to work correctly.

  1. in blueprints, dragging off pins will not produce the options menu for find a new pin.

  2. Right clicking to add new pins wont work

  3. The toolbar in the main screen - file, edit, etc doesn’t work - the menus don’t drop down

  4. In the landscape editor the menus don’t drop down… in fact none of the drop down menus are working at all. Every time I use the mouse to left- or right-click the titlebar of the window I am in highlights and unhighlights as if I am clicking outside of the window and then back in…

If anyone can help I would appreciate it cos this is very frustrating and I am unable to go into older projects and update, make changes or carry on working in them… Version 4.17 is working perfectly however.

thanks

I had this problem. It was actually a Windows update that auto installed itself overnight that left the UE4 interface broken. I had to rollback my Windows update to get the functionality back.
