Can't find View Only mode in v4

[Luke Wells]

Hi,

I am used to using the viewonly mode from either the windows viewer app
itself or by typing the -viewonly switch at the commandline.

Since v4 the option is no longer there in the viewer app and typing
vncviewer -viewonly at the commandline pops up a dialog box saying "The
option -viewonly was not recognized. User -help to see VNC Viewer usage"

So I did -help and there are no commands to do viewonly.

Have I missed something? Has it been removed from VNC

Thanks for any help you can provide

Kind Regards

Luke
