This has posed a puzzle with one of my applications that involve a lightbox with video configuration options Reproducible: Always Steps to Reproduce: 1. Navigate to the url above (Johnny Cash) or any other flash content site. 2. Execute the following in the address bar: javascript:void(document.body.style.overflow = "hidden") Toggle it back and forth between "hidden" and "auto" and you'll see the video reset. Actual Results: Flash content is reset Expected Results: Changing the overflow of a page should not cause Flash to reset Possibly related to Bug 156547?
