Suddenly getting script error on button javascript
For a couple of years we have had a button object in our skin, linked to our support page with the following javascript command:
top.open('http://www.ourwebsite.com/support');
Until recently, the button has worked fine in every OS we support (Win 7, Win 8, Server 2k8, Server 2k12).
All of a sudden, however, we're seeing a strange script error when clicking the help skin button on the two server OS's (2k8 and 2k12). Both OS's are the latest, fully patched versions.

Any thoughts on why Windows 2k8 and 2k12 would suddenly start throwing this error?
