I think from the original discussion, the card is not really "live" yet, in that it has not been loaded into memory. So the object exists, but has not arrived. This is earlier than what you characterized as simply not shown yet. Rather, it isn't yet. The "mouseUp" message would have been sent into the ether, and would not have thrown an error, just as if you say: send "mouseUp" to this card where no handler exists to trap it. As I understand from Peter's original post, he did not send the message to an explicitly identified button, which I assume would indeed have thrown an error. Or at least it should have. The only strange thing, derived from my incomplete understanding of just what and when stuff is in existence when "preOpencard" runs, is why the "dispatch" command showed "handled". So, similar to my little test above: on mouseUp dispatch "mouseUp" to this card --no handler anywhere answer it end mouseUp yields "unhandled". As it should.

The whole reason for the preOpenCard message in the first place is to be able to initialize/format stuff on the card before showing it. Now if a control hasn't yet been *created* that's one thing, but otherwise you should be able to configure controls before the card is displayed. Hope I'm not confusing the issue.
