Yes, the object is a depth 1, so that makes sense.

I've done a bit more testing today, and the replace_display_object error might just be a symptom of a larger issue I'm having. After the second load of the sub-SWF containing the DataGrid, the destination MovieClip has a width and height of 0 -- and I cannot resize with actionscript.

I verified that when I register my MovieClipLoader listener, the destination clip's size is valid:

22106:3085941184] 16:04:58 TRACE: myListener.constructor:: dest w/h=[501/701]

but by the time onLoadInit() is called, the target_mc is set at 0 and I cannot change it:

If I remove the (empty) DataGrid from frame 4, everything works just fine.
