Hello.

Thank you for your help.

Your instructions fixed the problem.

I had the impression that (and, I should probably have tested it, rather 
than making, and getting stuck by, the assumption) the screen that I 
previously saw, indicated that konqueror would not work.

Thank you for your clarification, and, the instructions for how to 
overcome the problem.
