Sorry, I should have specified that. The problem occurs in both IE6 and IE8. (I didn't test on IE7, but I assume it's the same.) I don't think the problem is due to the lack of PNG transparency support in IE6, since it also occurs in IE8; but is perhaps a subclass of that problem related to transparent PNGs under animation.
Again, when I use an ImageBundle with a single image, it works. However, when I add a second image to the ImageBundle, the problem occurs. Perhaps there is a GWT bug with fixing PNG transparency for IE for ImageBundles with multiple images. Someone on a Scriptaculous forum seems to be having the exact same problem (although, the thread contains no answers): http://groups.google.com/group/prototype-scriptaculous/browse_thread/thread/e4822eaa34a97839 On Jun 10, 10:47 am, Jason Essington <[email protected]> wrote: > Which version of IE?
