Unspecified error invoking method or accessing property: showWindow

I have users that are getting this error with Pop blocker turned off in 6.7. Whats stranger is the same users are not getting this error when using 6.5.2. Any ideas?

Found issue so I thought I’d add it here for future reference. The users have the google toolbar installed and it was overriding the IE settings. Added Allow pop ups for the CMS site and restarted browser and this resolved the issue.

I also was getting this error message from the Yahoo! toolbar as well, but only for certain items. Other items would open and edit without trouble… running on 6.7
