Handler won't execute from card or stack script

[Ian McKnight (MM)]

Hi all.

I am experiencing some strange behaviour with a handler on which I hope 
someone can shed some light,

The handler has two parameters and is called from a mouseup handler in a 
button script.
When the handler is placed in the button script along with the calling 
mouseup-- everything works as it should. However, when I move the handler 
to the card or stack script I get the following error


   There was an Execution Error at 4:38:21 PM
Error description:  Object Name:
Object: card id 1002 of stack ".............1/AptasXP 1.1.9.rev"
--------------------
-- Note: --xxxxxxxxxxxxxxxxxx <**>
--------------------
Value: hMT


BTW - <**> this line is the first line of the card script (or stack script 
)where ever the handler is placed and is a commented line.
  hMT is the handler name which I changed to rule out any possibility of 
handler conflict.

I'm using a licensed version of Rev 1.1.1 on a PC running Windows XP.

I can't think what would be interfering with the message path.

Any light would be very welcome.


TIA
