Kevin,

This has been bother me for quite awhile.

Why does my code for a pop-up window from my app not get blocked by IE SP2
pop-up blocker or the Google toolbar? (Yet some other pop-up blockers that
my users have installed does block it)

(No exceptions have been made in IE's Pop-up blocker settings either)

    Private Function openNewWindow(ByVal url As String, ByVal windowName As
String, ByVal features As String) As String

        ' url parameter must be enclosed in single quotes!!!

        Dim sb As System.Text.StringBuilder = New System.Text.StringBuilder
        sb.Append("javascript:var " & windowName & " = window.open(" + url +
",'" + windowName + "','" & features + "');" & windowName & ".focus();")

        Return sb.ToString()
    End Function

The code is not really important here. I think I might be missing the big
picture; are pop-up allowed if they are user initiated. (i.e. a user click a
hyperlink that causes the pop-up)?

BTW, here is a great link I saw yesterday to encapsulate creating a pop-up
into a class:
