KB and I are fighting in the Pubski from last week, and I'm not getting notified that there are new replies to read... my hubwheel stays blue and doesn't show me new comments. But if I go to the Comments menu, then I see he has replied to me.
The hubwheel next to my name turned Orange to indicate new replies for the first, and maybe second response. But it isn't lighting up to show me I have new responses anymore.
Is it possible that when you turned off email it somehow turned off notifications of replies?
