Some qlikview users can't see the tabrow with IE or AJAX
Today while I was changing some security filters and adding new users to my XLS-based qlikview security, I happened to notice that some users don't see the tabrow when logged in with the IE Plugin or the AJAX zfc.
If I log them with the Java Client there is no problem whatsoever and the tabrow is visible.
How can I reset the document properties (or what else?) to make the tabrow visible with these clients and users?
