Hi all.
I have a laptop with an external widescreen monitor attached. I run DOpus on the widescreen monitor because of the extra resolution. I have Opus configured that when I close the lister it minimizes to the tray. When I open a new lister, it comes up on the laptop screen, not the external.
It's a minor inconvenience to move it but it would be nice if the lister came back onto the same screen as the last one 
Can this be done?
Thanks!
I'm assuming the taskbar is on the main laptop monitor, meaning the mouse pointer is on the laptop monitor when you double-click the tray icon and you want the Opus window to be on the other monitor.
If so, go to Settings -> Preferences / Launching Opus / Default Lister and:
[ul][li]Turn off Update Default Lister automatically when closing a Lister.[/li]
[li]Select Always in the same position.[/li]
[li]Click OK.[/li][/ul]
Then, open a lister and maximize it on the external monitor as you want it to open, and finally use Settings -> Set As Default Lister.
That should be all you need to do, assuming the tray icon is opening the default lister (not a custom layout).
Your assumption was correct, as was your advice
Exactly what I needed, thank you very much!
