The Distance mode works a little differently. You click, then move the
mouse. The stuff gets drawn without the mouse button down. You can
then click again to set another point, with the angle and current
distance being tracked from the last mouse click, and a running total
distance from the first mouse click.

Yeah, that's a bug in the build.xml file. The BrowserLauncher is/gets
compiled but wasn't included in the jar file. It's been fixed for the
next version. You can modify your build.xml file by modifying the
section on creating the openmap.jar file (around line 105) to look like
this:

        <jar jarfile="${openmap.home}/lib/openmap.jar"
             basedir="${openmap.classes}"
             manifest="${openmap.home}/share/manifest.txt"
             includes="openmap.properties,
                       **/*.class,
                       **/*.gif, **/*.png,
                       **/*.properties"
             excludes="${corba.excludes}"/>

The ~/openmap.properties file should work and is the easiest. You have
to add a marker name to the openmap.layers property, and then create a
set of properties for that marker name elsewhere in the file.

Cool. Let us know how it works out.
