It's not a bug haha. The new page technically takes you to a new site (a new URL at least) and it randomly (to your blocker) pops up when you make a new page. I've been able to adjust the blocker to where it allows these on internet explorer by going to the tools page and just playing around in the pop up settings untill I got it to work. Unfortunately I can't remember exactly what I did (like I said, more playing, less fixing), but it does work for me now.
