When loading an AutoCAD drawing I get 2 errors 1, Can't find "genltshp.shx" and 2, can't find "ptmarks".  I know these are shape files in AutoCADLT, LTypeshp.shx, but they are not found in those files as well.  They don’t affect how the drawing is loaded.  They are just annoying every time I bring up a drawing. Does anyone know how to eliminate this?
