[Yars-users] Directed Camera Issues - Resolved

[Robert M. <rob...@gm...>]

Hey List!

Thanks for all the feedback!
It works. The last problem appeared to be due to my ssh X-Window  
connection. If i start Yars on the computer itself, everything seems  
to be fine. There is a window with a nice 1D camera output which  
appears to be plausible.
I'll report back later.
