Even when I maximize (with a unbuggy frame) I still see the title
line, is this windows vs kde? I can't see anything in kde system
settings which might affect this.

Sorry the context is after putting desktop-restore-frames to nil _on
startup_ the frame came up ok (as I said in the snipped bit of the
message you were replying to:

      Unfortunately after Juanma's suggested change (and then reverting it
      and an emacs restart) I get the frame *with* a minibuffer but without
      the window decorations.)

so it is there at startup but on 'maximize' (which isn't really
maximize) it disappears.

Having just tried it again (and the exit put desktop-saved-frameset
back). I'm again getting a single frame with no decorations and no
minibuffer I'll save that desktop file - it looks to me as if there's
only one frame now in the desktop file (at least there's only one
frameset--id which I assume is the determinant)
