Appears maybe due to it not executing the script that needs to set the sizes and render those gauges?
Body's onload refers to MyOnLoad, but I don't see that function defined in the scripts.
RemoteSensor does not seem to pass size attributes for the images in the generated HTML (nor width for many of the div's) so they do not scale properly (in this case using just the basic SensorPanel Core Wide panel). Using version 8.00.8000.
