Steps to reproduce
- Register an entirely new account (do not create it via the admin interface).
- Create some test posts. The default limit for the “education” dialog is 2 posts, after which you should no longer see it.
- The dialog continues to appear after the required number of posts.
- Now log out and log back in. The dialog will no longer appear for that user.
Perhaps this will help someone else in reproducing 
Sorry for “bumping” the post so to speak, but I thought the additional information might be helpful. I can also state that as of updating to v3.5.0.beta7 +139 the bug still appears to exist, at least on my end. I was also concerned that this may just have been a browser related hiccup (I normally use Safari), so I tried the reproducing steps with Firefox and the problem still occurred!
