If you select the entities first, pan to where you can't see them, select more entities and then issue the command you will lose those that are off the screen. If you issue the command first, select then pan. You should keep the whole selection set.
I am selecting the items without using the "select" command. Have always done this before C3D 2013 with no problem. Using the command does seem to work as it should though.
It's not the Select command. If you have PICKFIRST set to one and select an entity without activating any command you'll get grips. If you then issue the Move command you'll move all gripped items on screen. I'm sorry if this is covering basics you already know. But I want to make sure we're talking about the same thing.
I just tried a test in 2012 and couldn't duplicate the problem. This may have been an issue in an older version that was fixed and then broken again in 2013. I tend to develop habits that avoid an error and then might not notice when it's fixed.
There may be other conditions that trigger this. Here are links to the most recent posts I found when I searched the boards.
