Keyboard shortcuts set in System Preferences broken
I have set up a keyboard shortcut in System Preferences to trigger sending mail in the Mail application.
The shortcut works for a short while after the Mail app is launched, but eventually "breaks" so that when I press the key combo (option-command-s) nothing happens.
I have to quit Mail and relaunch it in order to regain the use of this macro.
This seems like a bug to me!
Can anyone help?
TIA
