createScreenShot captures overlapping window as well?

Before I moved this into the bugs forum, can anybody confirm to me that createScreenShot actually captures any overlapping window above the Irrlicht drawing surface.

For example, I have an application (windowed, non-fullscreen) that used Irrlicht to perform 3D rendering. I want to save the 3D rendering as image for printing, etc. thus I thought createScreenShot will be perfect to this. But I noticed that whenever there is any pop up window like tool window above the main window of my application, createScreenShot will capture them in the image output as well.

This is somewhat ugly. Does anyone has any workaround or any other methods to solve my problem?

I am thinking of using RenderToTexture for achieving my objective. But it seems that Irrlicht (Direct3D driver) still have this unsolve mystery that I posted long time ago.

Thanks in advance for any help.

USe OpenGL and all those problems will be immediately fixed...

So it is indeed a bug in the Direct3D driver?

I think it's a question of how the frontbuffer is grabbed. Don't know if there's a solution to avoid this, but at least OpenGL should have its own copy of the frontbuffer and hence be unaffected of rendering from other apps.
