From time to time I'll notice that I have a second instance of Opus open. I only want one. Can you tell me what I am doing that opens up a whole additional instance of Opus? When this happens and I hover over the Opus icon in the taskbar I can see two windows appear instead of one, so then I have to pick one and close it so that I am left with only one instance. Thanks.
There are many ways you can open a new window. It's difficult to guess without more information.
There are the obvious ones like clicking on the icon again in the start menu. I'm more interested in the ways that you can create a new window from within an Opus instance. Like if I am working within an instance of Opus, what are a couple things that I can do to open a new window without really realizing it?
This script logs all instances of listers being opened, which can help you determine the triggering event/action.
function OnInit(initData) {
initData.name = 'LogNewListers';
initData.version = '2025-10-01';
initData.url = 'https://resource.dopus.com/t/how-is-it-that-i-am-opening-up-a-second-instance-of-opus/57365/3';
initData.desc = 'LogNewListers';
initData.default_enable = true;
initData.min_version = '12.0';
}
function OnOpenLister(openListerData) {
DOpus.Output(openListerData.lister);
DOpus.Output('\t' + openListerData.lister.title);
}
