Here it is. It's under the animation event sheet.
When I open the event sheet in the latest version, I get some kind of error along the lines of "An invalid event was refrenced" or something like that. I basically can't scroll down or anything, and I can only see the first 6-8 events listed.
You may have to update, and then go through deleting or disabling events one by one until it works before I'll be able to help... or maybe Ash/Dave/Rich can test it out for you in debug mode?
