...which pretty much covers it.
It seems like the Fl_Text_Display needs to have room for two lines and use WRAP_AT_BOUNDS wrap mode.
I'm amazed that I haven't tripped over this before with textareas in dillo, but maybe two lines tall is uncommon enough...
Code to reproduce attached. | |

| Oh, also at one point I tried "#define DEBUG 1" in Fl_Text_Display.cxx, and then I was getting "*** display_insert/position_to_xy # GIVE UP !\n" from line 985 without changing wrap mode from the default, so it may be that wrap mode is not strictly necessary for position_to_line() unhappiness. | |
