Telling parent movie loader to load something

1

hi geniouses,

i basically need (urgently) to tell a parent mc to tell its loader to load a swf.

for the example, lets say swf1 loads swf2 through Loader1. i need a btn in swf2 to tell Loader1 (in swf1) to load swf3 (which automatically unloads swf2)

one more thing, does anyone know why my PDF download works in mac but not in windows? My code is:

this.PDF_btn.onRelease=function(){
_root.getURL(“Mami_TermLifePDF.pdf”,_blank,“GET”)
}

thanks so much! may life be good to you!
