When right-clicking a completed download in IDM and selecting Open folder, DO opens without showing the selected IDM downloaded file. Wait a few seconds or so, a second instance of DO opens showing the selected IDM downloaded file.
IDM must be running Opus twice in that case. Not something we can fix on our side.
It works perfectly in DO 12 though.
The mechanism hasn't changed from 12 to 13, and the only way two windows would open is if Opus is being run twice (or an API that opens folders is being called twice, or the API itself is going wrong).
I'm using the latest version of IDM (6.41) and the DOPUS 13 Beta (13.0.36) and IDM only opens a single lister when using right click > open folder.
Wonder if some sort of setting isn't importing correctly from your DOPUS 12 config. Have you tried backing up your current config and then resetting to default settings to see if that has any impact?
Explorer Replacement and the related config hasn't changed at all, as far as I can remember. It won't be a config issue on the Opus side of things.
Oh well, I'll be doing a clean Windows reinstall as soon as DO 13 is out of beta anyway.
The 13.0.37 update appears to have fixed it.
Don't know why that would have changed, unless IDM had an update as well. We haven't changed how Explorer Replacement works recently.
Glad it's fixed now, though!
Unfortunately, it isn't. It appeared to be solved, until I reinstalled Windows from a backup and installed the 13.0.37 update. The issue then returned and is still ongoing, very weird indeed.
