Odd.  And okay, KV Mk2 doesn't work well on K4, but on the K4/V4 mix,it works as well as on V4.  The YT version won't work on the K4.  I haven't been to 'Rotica for years, so I know I didn't get it there.  I don't use a  lot of sites, most of what I need I can find something here that will work,or sharecg. 

But, as I said, for what you want, a magnet might do.

Doric.

The "I" in Doric is Silent.
