This script is the most likely cause of the crashes. It's a bad idea to use
a script from the MIAW to forget the window - even if it's telling the
stage to do so. Director has to try to return to the script so that it can
finish any remaining code or 'end mouseUp' but the script has been wiped
from memory.
The method I use is to set a global variable that the stage monitors in a
looping frame or in the idle event. When the stage detects something in
that global, it then forgets the window. Something like the following
untested Lingo:
---MIAW Script
global gForgetMIAW
on mouseUp me
cursor(0)
sprite(spriteNum).member = overState
tell the stage to go frame "menu" of movie "nameofmovie"
close(the activeWindow)
gForgetMIAW = (the activeWindow)
end
-- movie script in stage movie
global gForgetMIAW
on idle
if NOT gForgetMIAW.voidP then
gForgetMIAW.forget()
gForgetMIAW = VOID
end if
end
I've seen others suggest using a timeOut object for this purpose, too. You
might want to search the archives for the messages containing that suggestion.
