CSS: white-space: nowrap does not seems to work in IE
For IE 6 and 7 you need to wrap your text with a <span> tag and give it a white-space property. Since you already have a <span> tag wrapped around your text and you have a class for it, just add the white-space property to your <span> class .linkColor.
.linkColor{
white-space:nowrap;
}
