I added a rectangle shape layer on top of a white background layer then I choose the type tool and click once on the rectangle shape to write some text. Instead of giving me the character type it gives me a paragraph text box. I didn't drag the mouse to create a paragraph text box. If I click anywhere except on the shape with the type tool selected I get a charter text. I am trying to create a navigation bar but it will not allow be to use the character type tool. how can I correct this behavior
