Pencil Project - Sketching and Prototyping with Firefox 3

firefox 3. nothing gets put down on the black page. no buttons or text areas, must be something in configuration. possibly web developer extension or adblock. any ideas?

thanks

never mind. i see now that you have to drag the object from the panel on the the canvas and then resizing it. as opposed to selecting it and then dragging the selector rectangle on the canvas..

it would be good if it allowed us to draw on the current page we have open as well.
