Sorry! Guess I should've been a little clearer. I've attempted to do something similar, but my issue also extends to the fact that I've added character portraits to the dialogue. Literally, the event I have set up shows one character speaking to another. It just gets really strange when the one character speaking is not the one intended (say, I want #1 to tell #2 something, but instead, #2 is telling it to himself, or #3 is talking to #2 in #1's place) ....does that make any sense?
EDIT:
After some inner deliberating and toying with the system, I've come up with a solution of my own. I'm terribly sorry if I've wasted anyone's time, but I now know of a way to bridge this issue, and will comment on it for anyone who needs it.
1- Whenever an event is created, the onscreen character should be set to an invisible/nonexistant sprite.
2- Create an event of the characters you want to act in this little cutscene. (Heroes 1 and 2)
3- With the onscreen character not appearing, while the desired characters' sprites taking action, the event should go by without a cinch.
