MY Lr is not responding to any process due to the following: Lr is asking " Delete the selected master photo from disk,or just remove it from Lr" the options are delete from disk,remove,cancel. Cancel doesn't work the other two options are deleting my photos which is not what it's required.
I am having this same issue. In my case, I click cancel and the dialog reappears. But after a few cycles the dialog stops coming up and LR then works fine. Goldlace, since your post is over a yea old, I assume that you were able to resolve. Any hints for me?
