It all looks great from here. The only problem I had was in the messages. I composed a message and before I sent it I pressed the ABC Check spell checker and the message I wrote disappeared, twice. It seems to work here though in the thread creation. I do have it installed but I noticed that when I use the icon in this header it has a pop up that tells me where to download and install it.
As an update the icon for ABC with a green check looks like the ieSpell icon so I have both spell programs and it looks like if I choose the ABC Check instead of the ieSpell it will delete my message only in the send a private message creation screen. Both work here in the thread creation and reply.
