Normally, I can highlight text in a terminal and paste it with a middle-click. In LyX, usually I can get to it with Edit -> Paste Special. (I can copy-and-paste fine in my xterms.)
In my LyX, the Paste Special choices are shaded out and not clickable. This is LyX 1.5.2 on NetBSD. I am not running any clipboard utility. Any ideas why I can't paste into LyX?
