When in a simulation all I see when I click on a link is a context menu that in which all the items are greyed out except delete and validate. What I expected is a option to modify the link parameters. I know this is probably some UI setting that has been inadvertently changed on my VMM client. I've done this before where I modified the links parameters to simulate trouble on the line, but right now I can't seem to get that option. Does anyone know how to get it back? I am running 1.6. If I right click on the simulation itself I get the option to reset all link parameters. I just seem to have lost the ability to set them in the simulation.
