I can't paste hostname into vncviewer from vnc-4.1.2-7.fc6.
Can you specify your problem more? (steps to reproduce, what you except)
When starting vncserver on a machine, it prints hostname:1 to be used in
vncviewer to connect to the server. I have to enter the hostname:1 by hand
into vncviewer, instead of cutting hostname:1 and pasting it to vncviewer.
Vncviewer's logging window isn't designed for more complex operations (like
cut/past) now. I think, This isn't a bug so please mail feature request to RealVNC.
