Hi Sarah,

I think I failed to convey the gist of my concern.

Stack "foo" was definitely in the wrong place. When I moved it to the 
right place, the error was solved.

The thing that caused confusion was the error message, which 
indicated that there was something wrong with the script:

On mouseUp
   do someStuff
   go to stack "abc"
   do someotherStuff
end mouseUp

There was nothing wrong with that script. There was something wrong 
with the "on openStack" handler of stack "abc" I can't understand why 
such a misleading error message arose out of all this. Maybe there's 
a good reason -- or at least a logical reason. If there is, I'd like 
to know it.


Cheers,


Tim
