the subject says it all - in a particular project, trying to set the end action on any timeline crashes the program (unexpected error).
Other projects do not have the problem, so rebuilding the project seems to be the only option.
Has anyone encountered this?
I had the same problem. I couldn't idenity the cause but was able to complete the project by assigning the end action using the 'assign link' in the right click menu rather than the 'end action' drop box in the Properties window.
