Where is my VS 2005 Addin Tool Window

[sebastian.dau]

Hello NG,

I'm trying to put my software tools into an vs2005 addin with tool
windows.

I use :

Windows2 w = (Windows2)_applicationObject.Windows;
_workItemWindow =
w.CreateToolWindow2(_addInInstance,
Assembly.GetAssembly(typeof(WorkItemToolWindow)).L ocation,
typeof(WorkItemToolWindow).ToString(), "SLCTools - Work Item
Explorer",
"{dc2dab7a-bdde-4dfb-affd-267830fa4875}", ref tempObject);

_workItemWindow.SetTabPicture(Properties.Resources .Tool);
_workItemWindow.Visible = true;

To init the window and it works. At least I get valid objects from the
methods.
However, I just cannot find the window in VS.

Does anyone know how to bring to front such tool windows?

I have Guidance Automation Tools and Extensions (CTP) installed, might
that be the reason for the problem?

Thanks in advance!

Sebastian
