I am experiencing some strange behaviour with some users on our SharePoint 2010 Enterprise. For some of them, the library tools menu is not displayed on the pages. All they can see is an empty frame. The Site actions menu works fine. The navigation menu works fine as well, including the display of the list views.
- Happens on IE9/Win7 for some users and not for others
- Happens also on IE8/WinXP for some users and not others
What I tried: - Resetting the browser settings to default; - Adding the site to Intranet sites and then to Trusted sites.
Any help welcome.
