Hi folks,
this is my first question in this community so please don't be to rough 
When using IE11 in one of our customers Confluence links in the sidebar get marked and not clicked on the first try.

As you can see both points are marked.
I clicked on "Alle Updates" and it just got marked.
Confluence is running on version 6.2.0
Anyone knows how to fix this?
Thanks for your help! 
Kind regards,
Louis
