Recently i've had a problem that I haven't been able to tackle. I'm using LDD 2004 and i'm having a problem with autocad not remembering previous selections. The undo command works just as well as it should so it remembers previous commands but not previous selections. For example, if I select a line, then activate the "erase" command, I have to reselect that line. Also, the delete key not longer works as erase. If I select a line(not in a command) then escape out of it and do a command like "move", when pressing "p" for previous it doesn't remember that I selected a line. If I move that line in a command, then do a move previous then it will remember it. Any ideas??? Thanks in advance, I appreciate any input.
