Launch DO9 with double-click not working in WinVista

My experience with getting a lister to appear when double-clicking the Vista desktop is that it doesn't work until I go to Preferences > Launching Opus > From the Destop. I check the "Disable" radio button, click "Apply", then check the "Open the Default Lister" button and click "Apply" again. Double-clicking now works for a time. At some stage it seems to stop working again; I haven't yet figured out what might be linked with this loss of the double-click function.

I have never set any .exe file for Dopus9 to Run As Admin, nor any compatibility mode. And when I check these files that is confirmed, no compatibility and no RunAsAdmin.

However, I DID set the DO8 instance to "run as admin". But surely that is not remembered anywhere. Especially as I have now uninstalled completely on multiple occasions now.

I am now running permanently with UAC turned OFF, so that I can use DO9. But that's not something I really wanted to do. UAC is a pain during the first 7-10 days of running Vista, while you are installing all your progs, etc. But after that it doesn't interrupt much, and does what it's supposed to do ie: protect your PC from malicious apps running without your consent.

I think the DO team have been inundated with requests since the release of DO9, so Im gonna run with UAC off for a while, until everything settles down, and hopefully a fix crops up.

Quad, you and had it the same. Somehow I got around mine. But I couldn't tell you what fixed it. When I get time I'm going to install Vista in virtual PC and take another look. But this is going on the back burner. Jon's swamped anyway, as am I.

If you set the Opus 8 exes to run as admin and then installed the Opus 9 exes in the same place -- even if you uninstalled 8 beforehand -- then it looks like Vista will remember and apply the setting to the new Opus 9 exe. But if you've checked it's no longer applied then it can't be that.

Just found one way of stopping Opus 9 displaying a lister when the desktop is double-clicked: Reboot Vista. After rebooting, the double-clicking needs to be reactivated from the Properties dialog as explained above. It seems quite reproducible.

You must let the dopusrt.exe helper app run on startup. If it is blocked by Windows Defender or other anti-spyware software then double-click will not work until Opus runs.

You can use the Task Manager to verify that dopusrt.exe is running after startup.

Thanks for the suggestion, Jon, but that ain't it: dopusrt.exe is definitely running on reboot, but the double-click action doesn't work until I get it going using Preferences.
