I've written a script based on jquery and the benalman jquery hashchange plugin that allows us to go from one page to another whithout stopping videos that may be playing. THIS is the site where I use my script. Click on a link that starts some music, then go to another page using the menu at the top, to the left. You'll notice that the music does not stop.
This works in all modern browsers except Opera. The pages that are supposed to load (in an iframe) often hang with that browsers. There's no Opera problem on the hard disk. Does anyone know if this is an Opera bug?
