SCRIPT70: Permission denied in IE9

System

We are still using TeamSite 6.7.2 Service Pack 2 and are having some issues when we add metadata to our files.

If I select a file and select File > Tag, I see the tag form. But if I close it and do one right after that I see a blank form and have these javascript errors:

SCRIPT70: Permission denied
dcapi_iframe.js, line 68 character 5

SCRIPT70: Permission denied
dcapi_event_tagui_multi.js, line 3 character 1

SCRIPT5007: Unable to get value of the property 'debug': object is null or undefined
iw.ccpro.tag, line 257 character 9

This is only happening in IE9. Does anyone have any suggestions?
