I prefer using Opera instead of Konqueror for my web browser, so I set it as the default. But now when I go to view system info, it gives an error (saying it does not know how to handle that protocol). Any idea how to set this up?
I suspect this is a KDE feature. There is a file getsysinfo but there is no man or info file for it and all the other references to sysinfo on my computer are in KDE (or Windows) folders.
You could try KDE forums
