I have had a very odd issues for sometime and have yet to figure out why it happens.
It's doesn't really hurt much but surely there is an issue there which could lead to other issues and that is what I would like to avoid.
When I am in the dashboard and click add new post, the admin bar goes away. (see screenshot)
I have the most current WPMU and buddypress installed.
At one point while troubleshooting another header area issue which I believe I may have posted here about, I disabled all the plugins and the issue I am posting about now was still there. I have since tried a couple other options here and there but it still goes away.
This does not happen on any other areas that I have seen. If anyone knows what causes this and how to fix it please let me know. Thanks.
