Frank,

>Any idea on why this may be happening? Is there a best practice for how to customize the MM forms included in the framework? Should we take a different approach?

As Tim mentioned, if you can provide more details about what you’re looking to enhance, it would be easier to provide a solution for you. That said, if you take a look at the Mere Mortals Framework Windows Forms project you will see there is an ILayer folder that contains an ILBaseForm class from which mmBaseForm (and therefore all MM .NET forms) are derived. You can make changes to this class and all forms you create will inherit the change. Obviously this requires you to recompile the Mere Mortals Framework Windows Forms project, but it’s a better approach than copying the MM .NET source code into your custom project.

Best Regards,
