Title: EasySymantecMenu
Question: This article contains the unit EasySymantecMenu. This is a look-alike to the PcAnywhere 11 leftside menu.
NOTE!
You need the other posts to be able to compile this components.
You must disable the Compiled Resources (*.dcr) to compile this components. I'll send the dcr's to the admins and tell them to attach them.
