Open in new window

Hi all,

i try to make completely secure konqueror window. So no bars, no choices, nothing. It is almost done but one last thing...
When i click with a right mouse button to a folder there is option in menu - Open in new window. When clicked full featured konqueror window starts. How to disable this Open in new window menu entry?
 
It is almost the same as Open in a new tab, what is 
 
 [KDE Action restrictions][$i]
 action/openintab=false
 
 but no documentation i have found describes Open in new window. Do you know (or
 point me to better documentation) to show me how to lock this? 

Konqueror 3.5.1, KDE 3.5.1 (Level "a" SuSE)
 
 
thank you very much
 
 Honza
