All:
So here is another test. Make a brand new stack. Put this into the stack script: on mouseUp dispatch "mouseUp" to this card answer it end mouseUp If you start with a new session, opening the test stack from the finder, you will get an error: Type Handler: can't find handler Object Untitled 2 Line send "mouseUp" to this card Hint mouseUp There is no such card (yet); the card just does not exist. However, also in a new session, if you open another stack, and then open the test stack from the finder, all is well. So "preOpenCard" is invoked REALLY early, but it seems to matter when and how it is invoked as well.

I had thought about moving things into openCard. I already found I had to move some code that used libURLxxx from preOpenCard to openCard because of the library not being loaded. Didn't think of the visible part of it though, thanks for the idea.
