Keyboard Commands when form is disabled

[SME]

I am using a checkbox to disable all of the controls on a form if it is checked, but once this is done my shortcut keys (i.e. control+S) are also disabled. Any ideas as to why??

Well, if you disable all controls, then calling any of them with the shortcut is obvious not to work.

The application is a MDI app, and the shortcut keys I'm calling are on the main MDIForm, not the form whose controls I'm disabling.
