When you press the mouse down and them move the mouse (dragging), the status no longer is updated as there are no mouse move events. It is impossible to tell if the mouse has moved while the button is down. Reproducible: Always Steps to Reproduce: 1. go to http://lynnsoft.2y.net:81/mozerr/err2.html 2. put the mouse over the image 3. click and hold the left button 4. move the mouse while holding the button Actual Results: The cursor turns into a "no" symbol and the coordinates at the bottom remain at the poitn where the mouse went down Expected Results: The coordinates should keep updating because of mouse move events being sent
Add onmousedown="return false;" to the image and the problem will be solved. See Bug 114852, comment 9. INVALID?
