When jed is configured to use edt mode. i.e. .jedrc contains () = evalfile("edt"); edt-style functions bound to the numeric keypad do not work correctly when in application mode. For example, the period key of the numeric keypad should give a period when in numeric mode and should do a "smart_set_mark_cmd" in application mode. Instead, these keys work as if they were in numeric mode at all times. Those edt-style functions which are mapped to keys other than the numeric keypad work as expected. In particular, the "Gold" key (Numlock) writes a message to indicate it is correctly toggling between application and numeric mode. Note that xjed does not have this problem. (I have no jed related Xresources). With RH6.2 this problem did not exist either. However, downgrading jed and/or slang to the RH6.2 versions does _not_ fix the problem.
Does the failure in normal mode (not xjed) fail on both the console and in an xterm/gnome-term/whatever, or just under X?
I've just tested it under other terminals and the failure in normal mode only occurs in an xterm window, not in kterm, nor gnome-terminal nor on the console. Perhaps it is something with xterm then?
I can now confirm that the problem is not with jed, but with xterm. Downgrading xterm to the version from RH6.2 (leaving the rest of XFree 4.0 as in 7.0) fixes the problem with jed.
