Can't delete a stack

[Pierre Sahores]

from the dictionary entry for "Delete" :

 Important!  You cannot delete the object whose script holds a currently executing handler.

Can makes thing confusing in some cases ;-)

> Sadly, exactly the same thing. If the IDE can purge a stack, why can't I? Maybe the delete command fires some other handler I don't know about. I will try to reduce the thing to a very simple test. I'm using LC 5.5.4 on a Mac, by the way.
