[Qgis-user] how to edit .gpx

[M.E.Dodd]

Can load a .gpx but can't seem to edit it, the editing button stays greyed out (qgis 1.7).  can save to .kml or shapefile and do edits but then loose some info from the original .gpx
looking at posts it seems that editing gpx has been in qgis for some time but i can't see how to do it.
