A few months ago we launched cboqyouth.ca And I've just noticed (in Browserstack) that in IE8 and IE9, the main dropdown menus fall behind the feature slider of videos - and become obscured. Alas, for IE.
It seems to be a similar issue to the forum post
In this case, I also tried to use a z-index: 1; but couldn't find the right selector for this. Any ideas?
