For quite some time now, an hour or so, when I, for example, hit "Edit" on a post, it don't get the quick edit box, it takes me immediately to the Advanced screen.
Also, beside Quick Links, the small arrow is missing and the little scroll down menu under it is missing. When you click it, it reloads the page and the links on the AHS menu bar changes instead.
Posting a Quick Reply also re-loads the page, which it usually does not do.
edit,
it went away now, after around 1.5 hours. During the time hotkeys for bold/italics etc. did not work either (Alt Gr + B).
