All images broken in all CHMs

Hi,

What would cause all images in all CHMs in all projects to suddenly break? All the images in any CHM on my computer are broken, and they were fine last week. They're also broken for my colleagues who view the files on their computers. I'm using RH 10 with Windows 7 Enterprise, and nothing has changed on my computer that I know of (although the network could have pushed something to it).

Thanks,

Beth P.
