Can you draw POLYLINES in Global Mapper on Georeferenced photos?

I am finding that I can only draw straight lines. I need to create the outline of several curved roads on a georeferenced file but cannot figure out how to do this.

Is this something relating to a shape file?

Thank you,

    Here's what I do when creating new polyline features:

    1. Open GM.
    2. Load an image file.
    3. Activate the Digitizer Tool - the Edit cursor should be visible.
    4. Right-click in the image - select "Create New Line Feature"
    5. Create the polyline.
    6. Right-click to finish - add name,etc. for entity.
    7. Click OK.

    Now you can export the vector data to whatever format is available.

    I hope this helps.
