CommandKeyDown in a library script?

Graham.


Since 1987 you have been allowed as many similarly named handlers in a script, and certainly among the objects in a stack. If within a script, only the first one is exectuted by the engine.


This is acutally a good thing. You can try several variants of a handler, arranged one after the other, and test them, commenting out the ones above the one of current interest.

Craig - sorry, forgot to thank you for this. Yes, there was another handler 
further up the library which I didn't notice. The IDE did not complain that I 
had two identically-named handlers in the same script, which seems odd to me. I 
wonder if it's a bug? I think the IDE used to complain about this, didn't it? It 
certainly doesn't now (just to be sure, I just added an "openStack" handler to a 
stack script which already has one, and it compiled without errors). I'm using 
LC 6.6.2.

Thanks again

Graham

you send it explicity to a card or control on that stack. Are you sure you are 
not trapping it anywhere in the main stack? Or if you are, are you sure you are 
passing the message?
