User Can't Edit due to "Somebody Is Editing This Page"

["jkherman" <webforumsuser@xxxxxxxxxxxxxx>]

I'm the administer for this site, and my other user keeps getting these errors.

 "It said someone else (me) was connected"
 "It said JKHerman is editing the page"

 I don't have the pages open?  Why is it doing this and what can I do to fix 
this issue.

 If I increase his privileges, do I need to resend another connection key?

 Thanks!
