I usually delete objects in my drawing using the delete key, rather than 'E' or 'Erase' - recently it's turned into a hotkey that translates in the command box to:
Command: MIDP
Command: Line from the Middle of
Command: Specify first point: of
It's then in a state ready to draw a line.
Suffice to say, it no longer deletes!
I've tried the pickfirst variable command to no avail - anyone know what I'm doing wrong?
