Sorry to be so irritated by this but my goodness. I've had the new WordPress 3.5 update since the day it showed up on my dashboard. I love the new media manager WHEN IT WORKS. It's not my theme, it's not my plugins, it's not my cache, or cookies, or any of those things. It's just plain freakin annoying to be smack in the middle of a blog post and the "add media" button work fine one minute and then next thing I know it's not working at all and hasn't been for the past couple of hours.
It's been a month right since the update? You'd think with as many people that are complaining of this issue it would be fixed by now.
Seriously if someone has any suggestions besides the ones I listed above please let me know. I am a photographer so media is kinda a big part of my blog.
