This may be another case where blurring the natural dividing lines 
inherent between the engine and the IDE have caused confusion:

When the engine encounters an execution error it can identify, it 
consistently throws an errorDialog message, regardless whether it's 
being used at the moment to drive the IDE or a standalone.  Same engine, 
same messaging.

The difference is that the developer must include some means of trapping 
the errorDialog message in their standalone if they want notification of 
runtime errors there.

Since the beginning both MetaCard and Rev have provided an execution 
error dialog as an option for inclusion in a standalone.  A developer 
may also choose to handle the errorDialog message themselves, using 
either an answer dialog (which must also be included) or a custom error 
reporting dialog (which I tend to use).

So while it's true that any errors explicitly thrown by the developer 
using the throw command will trigger the errorDialog message, all other 
execution errors which would normally be thrown in the IDE will also 
trigger the errorDialog message, as reliably in standalones as in the IDE.
