How do I stop a macro without having the Macro Abort message pop up?

For Macro Express 3 click Options, Preferences, Miscellaneous and click on the Advanced Options button. Uncheck the “Macro Stop Abort Macro Message”, “Hotkey Abort Macro Message” and “Right Click Abort Macro Message” options.

For Macro Express 5 and Macro Express Pro click Options, Preferences, General and the Dialogs tab. Uncheck the “Inform the user when a macro has been cancelled” option.
