Web Panel different from Front Panel

I saw some behavior that surprised me.
 
I have a VI running on one PC.  It is just running within the Labview development environment (call this the "actual" PC).  I did the web publishing so that others could view the front panel through their browser.  On the actual PC, I moved the cursor I created to near the end of the plot.  It moves along staying a point or two from the newest plot points.  On the remote PC, the cursor stayed near the beginning of the plot.  It did not reflect the changes I made to the actual PC.  Both the remote front panel and the actual front panel showed second by second updates of the data, but the cursors did not match.
 
I attached two screen shots.  They aren't quite simultaneous as it took me a second or two to jump from one PC to the other to capture the screens.
 
I think I already had the remote PC web page up when I went to the real front panel and moved the cursor.  When I refreshed the web page from the IE button, the cursor then went to the position it got moved to on the actual front panel.
 
I decided to try the other way.  On the remote PC, I requested control of the VI, then moved the cursor to a new position.  The actual front panel did not reflect this change.  I released control of the VI back to the actual PC, still no change.  I refreshed the web page, the cursor jumped back to the position it had remained on the actual front panel all along.
 
This isn't a real problem for me as the cursor is not critical to the application.  But I think it is strange that the position of this cursor is different between the two front panels.  If it changes in one, the change is not reflected in the other.  I'm sure someone might have an explanation for this.

Are you using  Embedded, Snapshot or Monitor option for the Web Publishing Tool?

Hello Juan,

I was using the Embedded option of the Web Publishing Tool.
