Re: Need help with creating shape files OpenMap-4.4.1.

Hi Scott,

There is a release scheduled for tomorrow that might fix things, but I'm
also pretty sure that the package expects that the
OMGraphics, which have to match the type of the graphic list, be
themselves in a sub-OMGraphicList which is added to the top level list.
Typing is very important, and the next release has better typing control.
