Preventing Excel opened through webbrowser "taking over" other instances of Excel
 

I'm using the WebBrowser control in a Windows form to display an Excel spreadsheet. Most of the time this seems to work quite well. However, when I have opened Excel independantly of my application that instance of Excel gets "taken over" when I open my application and display the Excel sheet.

By "taken over", I mean that I can no longer interact with the instance of Excel that I opened idependently of Excel

Does anyone know a way of preventing this from happening?

It would appear that Application.Interactive has been set to FALSE; you need to set it to TRUE.
