The Help menu for PageMaker 7 doesn't always work under Windows either.
Currently on my home Winblows XP Pro system the Help doesn't work when I have Mozilla selected as the default browser for the system. I resort to creating a shortcut to the help main index file on my desktop for the rare times I need it to work.
Curiously the other newer adobe apps such as Photoshop 7 don't seem to mind Mozilla being my default browser and the Help opens just fine.
Adobe would do very well to get off their high-horse and either support Linux outright or actively support the efforts of the CrossOverOffice team! Their distain for their client base is starting to come through as much as Quark's....
