Alert.show() interesting behaviour

Question

I use multiple SWFs loaded in one main SWF. Each SWF is form
and its form is linked to a class that extends the form class.
Most of the forms use a base class. The base class includes a
prompt function that calls Alert.show(). The form class calls the
prompt function and when used within the SWF itself it works as
expected but when the SWF is loaded in a movieclip of the main SWF
then the message becomes the title and the title becomes the
message and everything else seems to be find.
I cannot figure out what the fuddle doddle is going on.
I know that some V2 components don't behaves as expected when
used in a SWF loaded into another SWF such as the ComboBox
component that requires a _lockroot to expand its list when clicked
if it's SWF is loaded into another SWF.
I suspect the same type of weirdness is going on with the
Alert component. I do have the _lockroot set but no cigars.
I also imported the mx.controls.Alert class in both, the base
class and the form class with no success.
Does anyone know how to make this work?
Also, dos anyone knows of a list of SWF loaded into another
SWF V2 component quirks and their solutions if any?

Answer 1

I should add that if I use Alert.show() directly from the
form class the it is working fine. It is only when I use it in a
base class function such as 'prompt' called from the form class
that it flips the message and title.
