CorelDRAW X5 :: Text Wrap Around The Map?

My text will not wrap around a map that I have created in CorelDraw. The map consists of lines (depicting roads, streams, and railroads that were drawn using the freehand pen) and place names and titles. In both contour and square wrap settings, the text box only recognizes the text objects on the map and ignores all the line objects. I have grouped everything on the map and it shows as one object. Is there a simple solution so that my text will properly wrap around the map. This problem is holding up my publication schedule!
