Kevin,
There are two common cause for this:
1) Issues with graphic card acceleration (try switching off hardware acceleration via the GRAPHICSCONFIG command)
2) You have disabled all the swept paths reports
Vehicle Tracking only draws a small section of the path when dragging it around or editing it, the rest of the path is drawn using the paths own report settings. IF these settings are such that no body or wheel tracks are enabled then they are not drawn.
Either use the report wizard or select the path and use the vehicle tracking properties option to enable the reports. Hitting make default will save the settings for new drawings/paths.
