As of about 10 minutes ago none of the message composition controls would work (e.g., insert hyperlink, font formatting, etc.) I logged out and logged back in again and now they're completely absent from the area above the composition window and drag and drop file attaching is not working. If you "Go Advanced" it changes nothing and there is no ability to attach files via the usual button that pops up a selection dialog. Something's wildly amiss. It now seems that I can't post, either. I'm hoping that this edit will work so that I can mention this, otherwise I'm stuck.
