fTools "dissolve" not showing open layers

I am attempting to dissolve polylines from a shapefile using Vector->Geoprocessing Tools->Dissolve, however the dissolve tool does not populate the dropdown menu "Input vector layer" with my currently open layers. It is empty. When I pick Geoprocessing Tools->Symmetrical difference, the dropdowns are populated appropriately.
I'm using QGIS 1.7.3 on Windows XP Service Pack 3 installed from the binary installer. My fTools is 0.6.1.
I attached a screenshot of the failure mode.

What geometry have your layers? Dissolve tool requires polygons, so if there are no polygonal layers - no layers in selector.
D'oh. ArcGIS identifies the shapes as "polyline". I tried it with a polygon shapefile and it works just fine. :)
The QGIS Manual (http://download.osgeo.org/qgis/doc/manual/qgis-1.7.0_user_guide_en.pdf p. 155) does say that the dissolve tool supports "features". It might be nice if that was updated to say "polygons". The documentation seems very good.
Thanks for the help.
