KDe FILE AND FOLDER PROBLEMS

[gordon mcmanus]

Suddenly ,and for no apparent reason when I left click on a folder , the 
Konsole flashes onto the desktop momentarily and then an error message 
appears
MALFORMED URL.
or
APPLICATION IS A FOLDER BUT A FILE WAS EXPECTED.
I can open the files or folders but sometimes they open erratically and 
if I click "open in a new window ", invariably they all try to open with 
OPENOFFICE org 2. Everything is working O.K. on the gnome (ubuntu ) side 
of things.
Any Ideas please
