Totalfinder 1.9.0 toggle dual mode

Since TF upgraded to latest version 1.9.0 I cant toggle dual mode anymore. It is present in the view menu, but its greyed out. Any idea ?

Something strange is going on. The menu item should be grey if TotalFinder thinks no TotalFinder window has the keyboard focus.

Does it work when you restart via CMD+OPT+ESC and launch /Applications/ again ?

No, restart doesnt help. I tried also disable/enable tabs and reset TF to defaults, but no success.

What if you created a brand new OS user, login under it and launch there?

@cellentano did you manage to resolve the issue?
