You can CREATE CLASS FormManager as Custom then. Custom classes work great in the class designer. With the limitation I mentioned before you can't drop any other objects into it at design time. So if your form manager needed say a Timer object. If you derived from Custom it would have to be done at runtime:

this.AddObject( "tmrX", "cTimer" )

If you derived from Container, you could just drag the cTimer class and drop it into the manager class.
