Since the above mentioned commit, a detach from screen followed by a reattach (screen -r or by unlocking the screen session after lock), these programs behave weird. Emacs does display mode-line updates in the next line each time which makes the screen scroll off. This behaviour is with vga=normal. On vga=791, the breakage _toggles_ between detach-reattach cycles. I.e. emacs breaks after the first detach-reattach and works properly again after the second one. I have yet to test a current kernel version with this patch reverted because I am too sleepy right now to solve the conflicts. If you need further information to debug this, please let me know. Hannes
