Hi Upstream's bug tracker is back online.
The problem with the numeric keypad was introduced by the fix to upstream's bug #1300 [1]. You can verify it for yourself by building motif 2.3.4, including the patch below to disable the fix: --- a/lib/Xm/Transltns.c +++ b/lib/Xm/Transltns.c @@ -56,7 +56,6 @@ #include <Xm/XmP.h> #include <Xm/TransltnsP.h> -#define FIX_1300 /* This is the new-style translation table, which is used with * versions of libXt that have the :-production translation fix Unfortunately, this disables the keypad arrow keys again. Fortunately, the fix [2] for #1300 is not too big. It might be possible to fix it for both numeric keys and arrow keys.
