I can also confirm this problem.
I’ve got two computers, one running Windows 8 and one Windows 10. The problem exists on both.
For the Windows 10 PC I can’t tell if the problem began when it was updated from Windows 7 to Windows 10, but for the Windows 8 machine I know that everything
worked flawlessly when I installed the editor… But now same problem as mentioned above. Probably a windows update did mess the things up?
I tried a deinstallation and clean editor installation of version 1.51 but same problem again.
After recalling a scene strip assignment is no more possible.
