Use the EnumWindows Procedure

Option Explicit

Declare Function EnumWindows Lib "user32" (ByVal wndenmprc As Long, ByVal lParam As Long) As Long

Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" (ByVal hwnd As Long, ByVal lpString As String, ByVal cch As Long) As Long

Private Target As String
Private Target2 As String

' Check for a running app
Public Function EnumCallback(ByVal app_hWnd As Long, ByVal param As Long) As Long
Dim buf As String * 256
Dim title As String
Dim length As Long

    ' Get the window's title.
    length = GetWindowText(app_hWnd, buf, Len(buf))
    title = Left$(buf, length)

    ' See if this Window Is IE
    If InStr(title, Target1) <> 0 Then
         ' Internet Explorer is running
         ' Do What You Need To Do With It
    End If

    ' See if this Window Is Netscape
    If InStr(title, Target2) <> 0 Then
         ' Netscape Navigator is running
         ' Do What You Need To Do With It
    End If

    ' Continue searching.
    EnumCallback = 1
End Function
)
   
' Look For IE and Netscape.
Public Sub CheckForNetscapeOrIE()

    Target1 = "Internet Explorer"
    Target2 = "Netscape Navigator"

    EnumWindows AddressOf EnumCallback, 0
End Sub

WDB: Thanks...but I guess I'm a little "green". Where do I put this code. Do I add a module?. Can you please be more specific?

Yes,
  Add it as a module and then use the CheckForNetscapeOrIE()routine as needed.
