Note: Excel '03 SP2

I created a workbook in which each person who accesses it can use the
hyperlinks to find the information they require. Until recently, no issues
have been noted with the worksheet. Now several users of this worksheet can
no longer use the links. The information still shows up as a hyperlink, but
clicking on it goes no where. Additionally, these users are unable to create
hyperlinks in any Excel worksheet they access. The hyperlink box appears,
but the "OK" button never populates. Note: The worksheet still works on my
computer with no issue.

Thank you.
