hmm, Not what I see Send, dispatch, and call use the current object as the target if none is specified. It would only be the card if the card was the object sending the command. Throw this in a button, *on* mouseUp *send* test *end* mouseUp *on* test *put* the target *end* test When you click the button you will see that the message is handled by the object. If you send a message using *Any* form (send, dispatch or call) and do not specify a target, then the object that is sending (or calling or dispatching) the message is the target. Of course a front script is inserted before the target and can handle the message, BUT it is not "the target". Here is my current understanding of the differences in Send, Dispatch, and Call. If anyone could correct me, I would appreciate it. I think dispatch does switch contexts. It send the message to the object and it is processed along the normal message path. It does have a special use of the "me" object which can refer to a behavior. But other than that I am pretty sure that references are evaluated in the context of the receiving object, not the sending one. Send is different because messages not handled but the target DO NOT continue down the message path. Send does NOT resolve "me" to the behavior script if there is any. Like Dispatch the context is the receiving object, not the sending one. Call is really weird. Context is the CALLING object not the Sending object. And messages that are not handled by the target pass down that object's message Path.
