web page data missing

Hello,
 
  I built a web page for my VI that updates every 15 seconds, the monitor option.  At first everything is great (image [50]), but then after a few hours I get image [10].  The digital indicators update correctly, but there is no data in the chart.  If I go out to the machine and wiggle the mouse it starts showing the cart like in image [50] and everything is fine.  I have a screen save come on after 1 hour, I also have all the power saving features set to never turn off.
 
Any ideas of what might be killing the display?

It turns out that an OpenGL screen saver was causing the problem.  Once I changed back to a standard windows screen saver the problem went away.Smiley Happy
