HI MadanLal - it's currently 'checked'.
It sounds like the behavior you're using to try to see if it's checked or not, and logging out and back in so quickly, isn't allowing the system to display properly to you. We haven't been able to replicate this behavior of the dashboard when moving at a reasonable pace through the Dashboard.
We also haven't seen this box 'unchecked' any of the times we've reviewed it over the last several days, it's always been check and it's currently still checked!
We'd suggest clearing your browsers cache/cookies/history and then slowly try to access that setting - you will see it 'checked'.
