_width and _height not working after loadMovie command

i’m working on a map file and i have several different maps that can be loaded into my file by clicking tabs

they’re loaded as external .swf files via the loadMovie command

when i have a static map as a part of my .fla the controls work fine … pan, zoom etc.

when i perform the loadMovie and the map changes … suddenly my bounds are no longer respected by the pan function’s limits

it’s like it removes the width and height … but if the w and h were 0 i would think the pan functions would not work at all so it must be something else

anyone have any ideas?
