My erase command is not working properly. When I select one object, and then another the ealier object becomes no longer selected. I've gone thru the list of options when the "?" is selected, but none of the options bring it back to what I call a normal state, where you can select multiple options in a row. Any suggestions would be greatly appreciated.

Make sure PICKFIRST and PICKADD are both set to a value of 1.  That should take care of the problem one way or the other.

That worked thanks. I cannot understand how this got changed.

Probably a rogue lisp routine changed the values but did not reset them.
