When you insert a drawing object in Word, a drawing canvas is placed around it.
The drawing canvas helps you arrange a drawing in your document, and it's especially
helpful if your drawing consists of several shapes.
While you can easily delete the drawing canvas on a case-by-case basis (drag the
drawing object off the drawing canvas, select the drawing canvas, and then delete
it), you may wish to prevent it from being created to begin with.
To stop the automatic creation of the drawing canvas
* On the Tools menu, click Options.
* Click the General tab
* Under General options, deselect the last option; automatically create drawing
canvas when inserting AutoShapes.
