it works for me. Do these messages have a plan text part? Also on the mail preview screen or the full view screen you should see 2 icons next to each other one looks a bit like "< >" and the other is 3 lines, these switch between HTML and plain text, are those present? Do they work? Also try with all plugins disabled.
Sadly, I am still getting the multicolored weird layout stuff.
Blue, then green, then red indents instead of simple '>' carats.
According to view source, the message itself is plain text.
The only two arrow like symbols I have are previous/next message.
I have no symbol showing three lines at all, just three dots where the view source is.
Tried with Seamonkey & Firefox.
My opinion of IE/Chrome/Safari etc doesn't need airing here.
I am not in fact all that fond of FF, but at least in it I can kill all the %$&*% tabs.
I am suspecting I might have messed something when I installed it, but I do not recall making any changes other than database and domain when I installed.
Thanks for the effort.
