Browser Mode:IE8 Document Mode: IE8 standards
There is an issue in this mode of the IE and it is caused because the two inputs are with transparent background and there is a bug in IE where input with transparent background is not clickable.Therefore I`ve changed the background of the top input with 1px transparent png for IE8.
not working: // txtInput.style.backgroundColor = config.backgroundColor;
working: txtInput.style.background = "url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABAQMAAAAl21bKAAAAA1BMVEUAAACnej3aAAAAAXRSTlMAQObYZgAAAApJREFUCNdjYAAAAAIAAeIhvDMAAAAASUVORK5CYII=)";
Bug is described here: http://stackoverflow.com/questions/2098714/input-boxes-with-transparent-background-are-not-clickable-in-ie8
wow... thanks for pointing this out. When I get a chance I will test it and push the change
