I've been using 2011 for about nine months now. (finally updated from R14)I recently imported an IGES file and now my commands are all wonky.If I try to erase multiple lines/circles etc, it'll only do one at a time. Pick on one, go to pick on the next and the last one loses it's highlight and won't erase.Trying to trim; if you pick on one line as a border, the next one you pick cancells the last....Seems to be doing it on a bunch of commands in a similar fashion. What did I do???? What should I do?Thanks for lookingZippyEdited to add: Does the same funky thing on any drawing I open so I doubt if it's related to the iges import.... Must've fat-fignered some key.... Which one I wouldn't have a clue.

PICKADD is probably set to <0>.  Set it to <2> and see what happens.Dave.

You want both PICKFIRST and PICKADD to be set to a value of "1".They are system variables that can be changed at the command line.How did either or both get changed?  You could have used a poorly written lisp routine that reset the variables and forgot to return them to their original settings.

PICKFIRST only controls whether you can select objects before (noun-verb selection) or after issuing a command.  It won't have any effect on objects disappearing or not with new selections.  That's handled by PICKADD.
 
A PICKADD setting of "0" requires holding the SHIFT key down to add additional items.  A setting of "1"  will add new selections to the selection set.  With "1", holding down the SHIFT key will remove objects or selections.
 
AutoCAD 2011 added setting "2", and it works just like "1" except that when using the ._Select command, the entities remain selected when the command is over. Previously when you used the ._Select command then executed a command, you had to use _P to refer to the previous selection set. Now you can use the ._Select command, create a selection and then launch the desired command with the selected objects pre-selected.
 
Most people use "1" as John suggests.  Mine was a "just in case" option.

I always suggest changing/checking both as to avoid having to answer a second question regarding the "other" variable I missed.  Saves time.

Fair enough. 
 
You have to dig deep to find a good explanation of what is different about "2" in PICKADD tho'... the ACAD help file (at least on my 2011 system) has the same exact paragraph description for "1" and "2"!

PICKADD was the ticket. Dunno how I managed to change the setting. I don't even know what a lisp routine is much less what a poorly written one would be...Thanks guys.

There's a menehune near your computer then... that's a whole other issue.
