Thanks for your answer and sorry for the late response and the missing data in my initial post:
I am running ZCS Version zcs-6.0.5_GA_2213.DEBIAN5_64.20100131185825 (i updated my profile now)
I tried editing the shared files with IE 8 and Firefox 3. Neither of them worked
There is no error. Normal behaviour at saving a file is a green box dropping from the upper sinde of the window, posting "
filename saved". In my case nothing is done when I click the save button.
