                // Load the stencil we want

                // show the stencil window
                //Microsoft.Office.Interop.Visio.Window stencilWindow;

this bad boy seems to be causing the error, if i comment it out the stencil is still loaded, my problem is when i click other document tab i need to set the stencil to the current active document

            Microsoft.Office.Interop.Visio.Window stencilWindow = currentPage.Document.OpenStencilWindow();


i need to be able when i click my document tab to set the stencil to the active window,  i already have a method that check for the active document that we use to save or save as.

thanks for all your help in advance

regards
