Tom had difficulty creating a new Topic so I have copied a recent post… 
By the way, I wanted to mention I have new versions of WXSIM (11.8.6) and WXSIMATE (3.9) at www.wxsim.com.WXSIM has a change in the way it uses MOS advection in auto run. Also, both programs now enable use of VWS (with Weather Display still preferred, of course!).
A lot of people had been asking for that for a while, though I do think that a number of people have tried WD as a result of WXSIM’s use of it.
Cheers
