WPF

A Fix for the WPF MenuItem Disabled Problem

I just recently started using the WPF with .Net.  It is amazingly similar to the GTK that I have used on Python projects.

I encountered an issue when I started using menus; sometimes the menu items are disabled when they shouldn't be, especially after returning from a modal dialog.  Clicking on a blank space on the form mysteriously reenabled them.  Multiple Google sessions and even some time spent on the Microsoft web site didn't yield any positive results.  I followed all of the advice concerning Commands and CommandBindings but there was no change in the behavior of the menus.
