External .swf load problem

The file was working properly until I upgraded to 7.0.1 at which time the buttons stopped working. The initial movie load for

_root.currMovie = "home";

works fine, but none of the buttons work. If I take out that last bit of code and run the movie the user can select one button which loads perfectly fine. Afterwards none of the buttons work again. very frustrating. here’s the button code

on (release) { 
if (_root.currMovie == undefined) { 
_root.currMovie = "history"; 
} else if (_root.currMovie != "history") { 
if (container._currentframe >= container.midframe) { 
_root.currMovie = "history"; 

if its more helpful to upload a zip file of the files please let me know, thanks!:rabbit:
