DraftSight keyboard commands

1 [esc] key doesn't work so that I can't unselect entities in one motion or I can't interrupt the action during the command. Strange thing is that sometimes it works. It seems that it works after changing some settings. But it doesn't last so much anyway.

2 [delete] key doesn't work as well. so I have to use [erase] command each time.
