I have a Jump List issue I have not seen reported on here yet. After days of using Start8, my jump lists have not been working - for Office 2013 applications. For built-in applications I was not having an issue. I rebooted several times. I tried opening dozens of files of each application.
However, I then noticed that if I pin one of these same applications to the Start8 menu, then unpin that same application, jump lists will start to work. I have been able to duplication this with two applications (Word and Excel).
I originally had Outlook pinned to the top of my Start8 menu. I'm not sure if that is cause the problem or not. I'll need to test if the problem still occurs if Outlook is not originally pinned.
