I'm struggling with this. I've used the jquery sIFR plugin as opposed to sIFR it prevented conflicts with other jquery I am using on my pages.
It works fine in its prime function: replacing html text with Flash.
However, the .sIFR-alternate class is given an inline style of 'opacity: 0' which persists when flashblock is on. So alternate text does not appear. Neither does it appear when printng the page (yes I have included styles for sIFR-print).
I've tried replacing the opacity:0 inline style with display: none but this causes height issues with the output flash.
Any one else had this or have any ideas?
