I am a refugee from the now defunct Kanotix, so be gentle please

I recently installed to hard disk version 5.1x of Knoppix.

Logged in as "root" I was trying to write a simple BASH script when I encountered the following problem.

1) I created a BASH script called "restoreold.sh"

2) In KDE I right clicked on the file and set the permissions to r/w and executable( important!)

3) I check the permissions in Konqueror to verifiy that the file is indeed executable.

4) I edit the file with Kate or Kwrite and save.

5) When I check the permissions of the file I have just saved in Konqueror the executable status has vanished!!

6) If I do 1) through 3) but instead open up a terminal screen/window and use "mc" (Midnight Commander) to edit the file the executable permission is maintained!!

The maintainance of the executable status is the "expected" behavour that I learned using Kanotix. This is what I expect to happen if I am editing a simple BASH script.

Am I doing something wrong in KDE? Please help as having to chmod the script file to executable after an edit is a major waste of time. The best analogy is having to cold boot the system everytime to recompile source code!!!

Thanks for your help.
