My company just deployed a dozen Windows XP touch screens in conference rooms to control video conferencing systems. We're using all-in-one PCs with no keyboard or mouse attached, so the only way to wake from screensaver is to touch the screen, which is of course interpreted as a click.
The problem we're having is that the click is passed through to the top app -- our video conf control system -- causing the user to take some action (like hangup) that they didn't intend.
We do need to have a screensaver, the PCs are turned on 24x7, and the control app is visually very static. We expect a simple bouncing image screensaver to significantly lengthen the productive life of the system.
Is this something we can tweak? The screensaver content is a single bouncing image, so I'd be open to replacing the screensaver, or tweaking the registry, or (best) pushing the change via Active Directory (all the affected systems are already grouped into a specific OU).
