How do I select one of two imported models? I have two OBJ files.  I Imported the first, then imported the second right after.  When I try to do a shift-drag select on the second model, the first one gets highlighted as well.  Shift drag select doesn't even work on the first model.  How do I select the second only so I can move it next to the other?

Thanks for your time!
rebooted my system and when i got it back up, it was working fine.
