This is a (greatly cut down) use of ncurses in GAP (www.gap-system.org), where a cursor was disappearing and not reappearing.

can you try with 1.10 or 1.11? I think this was fixed in 1.10, which just moved to Stable today.

I can't get this to repro any longer with either:

printf "\e[?25lfoo"; sleep 2; printf "\n\e[?25hbar" ; sleep 2 ; printf "\n"

printf "\e[?25l\e[?1049hfoo"; sleep 2; printf "\e[?1049l\n\e[?25hbar" ; sleep 2 ; printf "\n"
