Recently I upgraded to Firefox 3.0, today to Firefox 3.0.4. Described problem arisen in Firefox 3.0 and hasn’t been repaired until today. Lots of bug reports describe some kind of problems with dragging and dropping images, but this is about *web developing* and moving objects using *JavaScript*. It seems like there is some problem resulting from interaction of user interface (comfortable images Dragging and Dropping) and JavaScript engine: The dragging and dropping (actually the dragging) of *images* (still talking about JavaScript scripting) works “no more” properly (it means it worked in previous versions – prior to 3.0)… I am using technique described at http://www.quirksmode.org/js/dragdrop.html. Problematic are only images – that means, only dragging image objects works improperly (that means, examples at minded page work). Please, take a look at my testing web page and you will see the problem: http://cec.truni.sk/drag_n_drop/ There is a “window” and a testing “text block”… The “window” can be dragged properly *only once*. Each next attempt to drag the window will fail with “No” mouse cursor image appeared… However, if you try to drag and drop the sample “text block”, it will work… And in addition to that, after dragging the “text block”, the “window” can be dragged again properly, but — again — *only once*… Thank you for your interest to solve this problem… Reproducible: Always Steps to Reproduce: 1. Try drag and drop image object at the page for the first time… 2. Do not touch the text draggable object… 3. Try drag and drop image object at the page for the second time… Actual Results: Image object refuses to move… Expected Results: Move the object properly infinite number of times… Theme? Noia 2.0 (eXtreme)
I see what you mean, but the problem is fixed on trunk. So the next major release won't have this problem anymore. You can try it out: http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-mozilla-central/
