If you haven't specified a Subject Name, as soon as one connects with some curves, the debugger will switch to that one. You can change this selection by clicking the Live Link Subject Name drop-down (in Editor or a Desktop build) or by typing LiveLinkDebugger Next in the command-line to cycle through different subject names (on other client builds)

Inside a client you can also use the command-line to show the Live Link Debugger with the command: LiveLinkDebugger Show

Optionally you may specify a Live Link Subject Name to start with in the command-line by using the command LiveLinkDebugger Show SubjectName (the name of your Subject).
