Popup window problem

I made a flash application with a button and this code:
on (release) {
getURL(“javascript:var newWindow=window.open(‘pageOne.html’,'pOne,‘width=400,height=200,left=0,top=0’);”);
Problem: A new page starts opening but is immediately replaced by an alert message:
“Internet Explorer cannot download - Unspecified error”

Javascript is enabled. I’m normally a good flash programmer. Tried a lot of times, need badly a help. Thanks in advance
