command

I have a ContextMenu whose items are all bound to commands and enable\disable correctly after ANY Command is invoked from another source but prior to, they are all disabled. So if I run the app, all the MenuItems are disabled but if I invoke any of the bound commands from another source (buttons, for instance) they become synchronized with the CanExecute code. I have no idea how to debug this. Any thought would be helpful!?!
