I'd be happy to try. I am not a perl guru so I don't really know what it means by 'class' in that context. What I would expect logically, is a variable or some way to determine the path to the desired browser that should be launched. That is what seems missing to me in the documentation. I don't know how to tell it to use IE or Firefox or whatever the default browser is. I assumed (yes this is a classic case of what that makes of 'u' and 'me') it had a way to determine it from the OS settings but apparently not. If that is the case then that complicates things as I believe finding the default browser would be a platform dependent function and better left as a configuration issue when using HTML::Display.
