This may seem really trivial, but somehow it really annoys me.
I'm somewhat OCD, so I can't bear to have any unread notifications. Sometimes, when I'm reading a post, and I see a notification, I'll click it, see what it is, then quickly return. However, the notification icon is still there, and I have to refresh to get rid of it.
Also, if I write a comment, then click a link on the page, then click the back button, I have to refresh to see the comment I made.
Yup. I know, first world problem... but it really bothers me. Besides, it's all in the details.
Is this due to the way that the browser caches pages, or a bug in stackexchange?
