Thanks. That looks correct for what you're aiming for.
Note that exiting and launching Opus is no longer the same as what happens during boot. If you run dopus.exe on its own then it will always open a window. Fully exit Opus and then use the shortcut in Start Menu -> All Programs -> Startup to simulate what happens during boot. (That shortcut should have the 'NOAUTOLISTER' argument within it.)
If you want to see what Opus thinks it should be loading next time it starts (if set to Open the Listers that were open...), view /dopuslocaldata/State Data/openlisters.oll in a text editor. That might shed some light on what's happening (especially if it isn't actually being updated, for example).
(/dopuslocaldata is a folder alias. Just paste that path into Opus and it'll locate the right file.)
