Why does MainMenu keep telling me it will quit for security reasons?
If you get an error message saying that MainMenu will quit because it’s security has been breached, then the most likely explanation is that you used an application or system tool that trims or otherwise modifies applications. Applications known to cause this problem include Monolingual and Xslimmer. To protect your system, MainMenu does not allow itself to be trimmed or otherwise modified by other applications. To prevent this error message from appearing, we recommend that when you run these applications you tell them not to modify MainMenu.
