Lots of my unwanted actions get automatically added to the NLA editor in 2.75 and its a bit of a pain to go in and delete them. Is there a good way to stop it happening or to delete the action from the action editor?
You asked your question in the wrong thread. To answer the question. You will have to take off the auto key frame function(the red record button) off. As far as the multitude of actions that was created, you have no choice but to delete them manually.
