Problem with getURL in ie

hey all

i have button inside a movieclip the makes the following call:
getURL(_parent.siteindex[_parent.site]);

and the code in the parent timeline is as follows:

site = 1;
siteindex = new Array();
siteindex[0] = "
http://www.yoursite.com";
siteindex[1] = "
http://www.mysite.com";

which all looks simple enough, right? the problem is that this works fine in the flash environment and firefox it does exactly what it should be doing, but in i.e. it does nothing at all. nothing at all.

i’ve since done a couple of tests, and even if i enter a regular url (“http://mysite.com”) instead of an expression, it does nothing. i’ve been using flash for four years and have never run into this before.

any ideas on how i can stop pulling my teeth out with frustration greatly appreciated.
