Re: [las_users] las_users: vector plots with las v7.0.3

Martin,

I know you've raised this issue before and I'm sorry it has taken us so 
long to reply.

As far as I can tell, the issue is simply that that display of vector 
variables fell through the cracks in the current implementation of the 
user interface.  The server reports their presence when the UI asks for 
the variables, but the UI does not display them.

We'll get this fixed as soon as we can.
