[RESOLVED] [2005] WebException halts execution

When I use this code...

VB Code:

Private Function CheckURL(ByVal site As String) As Boolean
        Dim request As System.Net.WebRequest
        Try
            Dim url As New System.Uri(site)
            request = System.Net.WebRequest.Create(url)
            Dim response As System.Net.WebResponse = request.GetResponse()
            response.Close()
            request = Nothing
            Return True
        Catch
            request = Nothing
            Return False
        End Try
    End Function

With...

VB Code:

MsgBox(CheckURL("http://www.google.com"))
        MsgBox(CheckURL("http://www.googlexyz.com"))

the IDE stops execution on the second URL and throws up the exception dialog box. If I step it forward, it moves onto the Catch correctly. Is there a way to prevent the IDE stopping when it hits a WebException? (It only seems to do this with a WebException). I'd like the code to proceed onto the Catch without my intervention.

If I build the solution, it works correctly (but then I cant do any debugging).
