Flash Context Menus

There seems to be a problem when you use spesific keywords in the context menu.

When I use :
[size=1] selected_menu.customItems.push(new ContextMenuItem([color=Blue]“Cut.”[/color], folderItemHandler));
selected_menu.customItems.push(new ContextMenuItem([color=Blue]“Copy.”[/color], folderItemHandler));
selected_menu.customItems.push(new ContextMenuItem([color=Blue]“Paste.”[/color], folderItemHandler));
It works - note the fullstop at the end of each word, when I remove the fullstop it doesn’t even display.

Is this some inbuild way of stopping users from using these keywords themselves?

How can I remove it so that it works.
