Jon Riper told me about a problem using kbasic on Linux.
Kbasic uses the Qt command openUrl
http://doc.trolltech.com/4.3/qdesktopse ... ml#openUrl
to show up the documentation and help. But it failed on his system. So here is his workaround:
> Help problem solved: I noticed the error message "Firefox not found," the

Thanks Jon!
