after I add a new .orm to my project, I always get this error, which does not go away:
Warning 1 Custom tool warning: No BuildItemGroup was found for this ORM file. Use the ORMGeneratorSettings dialog to add items to the group, or clear the CustomTool property. C:\Documents and Settings\Dev\My Documents\Visual Studio 2005\Projects\SBSSM\SBSSM\ORMModel1.orm SBSSM
I don't understand what this means or what I should do about it.
