Hi all!!  
I have a small slideshow, which works exactly like the one on the tutorials (the pictures load from a movieclip). above that layer where the picture load from an XML file, i have a mask layer which is divided into 4 separate squares.

The mask works fine, only until i decide to make one of these squares a movieclip symbol, in which case the mask is only applied to the other 3 squares (which are merely shapes), and the remainder of the loading picture is not visible from the 4th square (the symbol).

i tried to use

_onClipEvent (load) {  
image\_mc.setMask (square\_mc);  
}_

but it does not seem to work. Thanks for anyone willing to help.
