This function works perfectly on my pc in Internet Explorer, but not in Mozilla Firefox (they all stay yellow, ie indicated, however often one clicks it). I'm sure there's a simple explanation, but does anyone know what it is? Cheers.
I need to click on the "Update new posts" link and check the board, then click on the "Update new posts" link a second time - then all of the icons turn white to indicate "read posts". This is on Firefox.
