Is there a way to enable that? Specifically, we have a dual monitor setup that we would like to use for viewing 2 different screens at the same time.

What for Windows Version do you use? In your IIS properties on WebNavServer, how much Website connections are configured?

I have been able to successfully open multiple instances of web navigator on some machines, but not others. I have it working on machines with both IE6 and IE7. All are XP. I don't have any popup blockers enabled. The message is coming from the wincc server because it has the same appearence as other Web Navigator messages (ie, Loading Page, Connecting to Server, etc.) Also, I don't think it is the number of connections configured in IIS because it works from some machines and not others. Hmmmmm.......

Does it work on allcomputers with IE V6 and do not work on computers with IE V7? Do you open in IE V7 a new Tab or a complete new IE? regards Amno

If I launch Web Navigator from a link or a vbscript, I am only able to open one instance and I get the error message if I try to open another. However, if I open a new IE Window each time and type the address in, I can open as many as I would like. The script I use is as follows: Dim objExplorer : Set objExplorer = CreateObject("InternetExplorer.Application") objExplorer.Navigate "http://140.80.0.152/" objExplorer.ToolBar = False objExplorer.StatusBar = False objExplorer.menuBar = False objExplorer.AddressBar = False objExplorer.Width = 1037 objExplorer.Height = 770 objExplorer.Left = 0 objExplorer.Top = 0 objExplorer.Visible = 1 If you copy this to notepad, change the server address, and save it as a .vbs file, you can open Web Navigator in a clean full window rather than having all of the IE junk bars at the top. This is what I use in our organization rather than IE Shortcuts.
