Popup opening 2 times

I have a popup window created through a link (as the trigger). My web designer 10 is creating the pages so that it opens 2 times.

Is there a way to force this to open only 1 time? This appears to be happening only in Firefox.

trigger call code.

Code:

---

javascript:popUp('http://www.signstopusa.com/login%20page.htm')

---

Placeholder javascript code.

Code:

---

<SCRIPT LANGUAGE="JavaScript">

<!-- Begin
function popUp(URL) {
day = new Date();
id = day.getTime();
eval("page" + id + " = window.open(URL, '" + id + "', 'toolbar=0,scrollbars=1,location=0,statusbar=0,menubar=0,resizable=0,width=660,height=550,left = 500,top = 275');");
}
// End -->
</script>

I need to fix the double window opening. But also, is there a way to make this open as a smaller popup window in Safari (right now it opens as a tab on an ipad)?

Any help will be appreciated.

Could you post your xar/web file?

My .web file is too large for the upload (15+ mg).

It may zip lower, but I am not sure how much.

I'm not sure if this is related but in Web Designer 10 Premium I had a problem with links that open a page in a new window (using target="_blank"). It would open two copies every time.

I have since opened the same project in Designer Pro X10 and re-exported the website without any changes, and now it works correctly.

So if these issues are similar then it looks like it is a bug with Web Designer 10.
