title: Perforce error: File(s) could not be locked
body: <p>I have some new files I wanted to sync to our Perforce server. I have them in my workspace and Marked for Add. They show up in the changelist. But when I click "Submit", I get "File(s) could be not be locked" and that's that. </p>
  
  <p>As far as I know I have complete user permissions from this machine and admin/super access on my P4 account. Any idea what could cause this? Most of the advice out on the web dates back to pre-2010 Perforce. </p>
  
  <p>I am using P4V if that makes any difference. </p>
