On MAC on Left Side Panel is a link for "Read NIV in one year", putting cursor over it has the hand but it quickly changes to a pointer and the tool tip is displayed and you cannot click on the link to bring up the plan in calendar view. I can do so by going to Documents, Reading Plans, but not from the homepage.
Also, trying a smattering of other links on the homepage gives the same result. It's like the tooltip logic is firing and displaying and disabling the hyperlink.
