OK here is a new issue.
I wanted to add type shadow to the larger fonts for the opened tabs titles. Works fine in FF, Safari, Chrome and Opera. But infogrid dies in IE, no tabs will open.
This is what I added in the infogrid.js file
In the allTitles.animate area.
"text-shadow": "0px 0px 0px #ffffff",
In the el.animate area. (only the open tabs with larger type will have the type shadow.)
"text-shadow": "0px 1px 2px #e5ebf1",
