Destroyer25, your post isn't helpful. At all. If you are going to post in the WEHZ, please try to do so respectfully, and in a way that is actually helpful.
Denigo, as to your problem, where does it crash? I'm also using 10.5, and it crashes if I click off a trigger after naming it, which can be avoided by hitting return after entering a trigger name before doing anything else. But I get the feeling your problem may be somewhere else in the trigger editor. Any more specific details could be useful.
