I use open motif 2.1 on Linux RedHat 8 for PC.

When NUM LOCK or (and) CAPS LOCK keys are ON, some Xevents like
Mouse 2 down or Key Echap and Key Enter (and many others) don't work

For example : I use translation on Key Echap to close a TopLevelShell. It
work when
NUM LOCK and CAPS LOCK are OFF but it doesn't work when they are ON.

If you know this problem and if you have a solution, please let me know
about it.
