IE - Webmail signatures

Hey,

My work colleague uses IE for her webmail on a Windows 7 desktop. We all use the same spec PCs, I use Firefox and use the same webmail for job@companyname.ie

We all have email signatures such as this:

Name
Post Title

Phone
Web
Link to FAQs

The problem is her signature links don't work, they're just dead text. This seems to be an IE issue as it's fine if she tries Chrome. I don't know why. I reset IE and had a look around for obvious things re images not displaying, etc. Like many of us, she defaults to her main browser, IE, rather than Chrome. I removed Ask crap bar today. Bing's her default search for some reason, she mightn't like this, but I couldn't seem to add a Google ad on as a search provider. [/tangent]

Trying to get this sorted as my boss wants all our signatures standardised. Any ideas?
