i am using full i did what you suggested but it still doesn't work
I am in a wonder about what you are doing, and about what you are trying to do.
So, you can edit Openbox menus several ways : by hand, or with the help of guis. You will have to distinguish between the main Openbox menu : the one you get first when you do a right click on desktop or on panel, and the submenus which are the one when you reach the first sub-menus.
The main menu, as well as most of the shortcuts with keyboard and mouse are ruled by the file ~/.config/openbox/menu.xml, and the submenu shortcuts are ruled by the file ~/.config/openbox/rc.xml.
Then there are a few more possibilities : wether you are using a PCLinuxOS Lxde, or using a PCLinuxOS Openbox. This is not the same, because on Lxde version it's Openbox vanilla (original configuration with original files) which is used, but in PCLinuxOS Openbox the right-click menus are ruled by the program openbox-menu, and the submenus are updated dynamically (=automatically).
So my next questions are simple: what PCLinuxOS version do you use ? What exactly is that you would like to change in the menus ?
