I just discovered that my short cut menus don't work. (I'm new to AutoCAD 2008 and didn't I was supposed to have them.)

Here's what I've checked:
-- CUI:
"Shortcut Menus" is present in the tree in the "Customizations in All CUI Files" window
and is populated
-- Tools > Options > User Preferences
Shortcut menus in drawing area is checked
-- Tools > Options > User Preferences > Right-click Customization
Default mode: Shortcut menu
Edit mode: Shortcut menu
Command mode: Shortcut menu enable when command options are present
-- SHORTCUTMENU = 11

So why don't the shortcut menus work?

What brought this all up is that I want to flip the arrows on a dimension. I am now so frustrated I am about to do something rash: Please, somebody save me from exploding the dimension and fixing it manually...

Best regards,
