Query: Targus does not issue drivers for my Viewsonic v37

It worked OK for 2 months, but the KB kept on falling off. When I complained, I was told that the KB was not compatible with my Viewsonic v37. Yet, it was advertised as compatible with the VS PPC 2002. The worse came when I upgraded to PPC2003 and the KB stopped working. I contacted Targus and was told that they do not have plans for upgrading their KB drivers for this VS PPC.I do not believe that this should be permitted. If you sell something, stand behind it.Very disappointing.
