I'm sure this has been covered before but as usual I can't find the info anywhere

Let's say I have a web page that lets you add and delete site members

When I click delete it pops up a dialog with OK and Cancel asking if I really wanna do it.

It's fine in IE but doesn't work in FF

So I tried something like this

Set BrowserDesc = Description.Create()
BrowserDesc("title").Value = "Internal Trial Site"

Set DialogDesc = Description.Create()
DialogDesc("nativeclass").Value = "#32770"

Set WebButtonDesc = Description.Create()
WebButtonDesc("name").Value = "OK"

Browser(BrowserDec). Dialog(DialogDesc).WebButton(WebButtonDesc).Click

But that does nothing. So what's the RIGHT way to deal with this?
