Suddenly tonight the LR Classic program has stopped even changing the window from Library main to the import section when I hit the Import button. Despite multiple system and software resets following the problem instead it is only now displaying the (NOT RESPONDING) up on the window title. On Windows 10. Had worked fine earlier today. LR is stuck in another of its refusal to leave the main library loops, and I am wondering if the new logo should just be L (NR).
