FAQ #2.9: 

When I try to access the "Help" feature in VisionGauge^®, the Help window appears with the index, but I am unable to view any of the help pages. I am using Windows XP with Service Pack 2 (SP2).

Windows XP's SP2 update disallows "active content" from being viewed across a network. If you are running VisionGauge^® over a network instead of on your local computer, you will need to either access the help file from the computer on which VisionGauge^® is installed, or copy the help file to your local computer to run it. The help file, VisionGaugeHelp.chm, is located in the main VisionGuage^® directory (usually C:/VisionGauge) in the Help folder.
