Nis 2013 bug Settings not opening

When I log into my Windows 8 64bit. Some times the settings page wont open. Login out and in again makes it work

again.

 

I have repaired installation but no problems is found. I have also reinstalled the program but the problem always comes

back.

 

This must be a bug whit Nis 2013 and Windows 8 64 bit.
