OK..... follow these instructions......
First, choose an icon that you want to use to open "My Computer". Make sure it is a Desktop X object.
Right click the icon and choose "Properties" from the menu.
A new window will open, and it will already be on the "General" tab.
Where it says "Object Type", click the "change" button.
Another window will open. In the dropdown box, choose "Shortcut". Check the box that says "Folder Shortcut", and then, from the dropdown menu at the side of that, look for My Computer. (Do NOT check the box that says "open as pop up menu).
You are done, and your object/icon should now open your My Computer window.
Have Fun!!
