I wasn't aware that Visio allowed you to edit
bitmapped images... but if you had originally pasted your
image in from another program (as an OLE object), when you
double-click on that object, the container application should
boot up, and the toolbars on the screen would change as well.
Perhaps that is what happened.
What kind of features did the toolbar have? Did you create the
image in another application?
