Freeze loading 3rd folder into Opus from outside (11.13 x64)

/acmd is an argument for dopusrt.exe not dopus.exe, and would take an internal command line as an argument, not just a path.

There should only ever be one dopus.exe instance and possibly one dopusrt.exe instance (outside of brief moments where another runs, passes information to the main dopus.exe, then exits). (If multiple users are logged on at once then there will be more, one set per user.)

Does the problem you are seeing only happen with specific folders?

No. All folders.

So if you run:

dopus.exe C:
dopus.exe "C:\Program Files"
dopus.exe "C:\Windows"

Opus freezes on the third one?


I will do that test now.

Yes, that is what happened.

Opus isn't running elevated is it?

You mean process priority. Yes, I did. I will try running it at normal and see what happens.

Or do you mean as "Admin". Yet, it is. I cannot change that, since UAC is shutdown and I run as the built-in Admin which always has the security token.

I just tested process priority and it makes no difference.

Jon meant UAC, but why was the priority changed from normal? What else has been changed on your system?

Lot's of things of have been changed. It is a PC after all.

So, I gather that you are unable to reproduce the problem?

Changing process priority is a pretty weird thing to do to a file manager, though. Anything else like that? What was it done to achieve?

Any tools installed which modify normal Windows behaviour, like custom window handling, extra gadgets in the window borders, things which monitor or are "invasive" into other programs' UIs, and so on?

Correct, we cannot reproduce what you're seeing. There is nothing special about the third folder to be opened and no reason it should cause a lock-up.

The issue may be with a shell extension you have installed (ShellExView is a tool that can list and enable/disable them).

Just to get fast response over background processes.

I will find ShellExView and send you a dump.

I have WindowManager installed which replicates the old open folder behavior of XP on the desktop. Remembering locations and settings.

I have Ultramon installed for dual monitor support, but I have yet to pick up the second monitor.

I am just going to use Explorer++ for these shortcuts. Thanks, anyway.

That should not be needed, as the foreground process gets a priority boost automatically in non-server versions of Windows. Messing with process priorities is usually a bad idea.

Best thing to do is disable all the non-Microsoft extensions, then reboot, and see if the problem remains. If it does, you've ruled them all out and can enable them all again. If the problem is gone, that says one of them was involved; re-enable half and try again, then repeat until it's narrowed down to a particular extension.

That could be very relevant, since it involves file manager windows.

Opus registers itself as a file manager window, and WindowManager may be doing something it shouldn't, by assuming the Opus window is an Explorer window and sending it messages that mean different things to Opus, or similar. Please uninstall that software, reboot, and see if the problem remains. If the problem is still there, you can re-install it after the test.

Ultramon is probably not involved, but it might be worth testing without it all the same.

Leo,

Thanks for your help!

I will give those things a try when I get a chance. I want to ask you do you think that reinstalling might help. You know "he installs last, installs best"?

If so, then I just backup my configuration? Uninstall/Install. Restore the configuration. Will it take my certificate again?

Thanks.

I did the test you proposed with ShellExView and it made no difference.

Thanks for trying that test.

Please do the other tests to see if WindowManager or Ultramon are involved.

Re uninstalling, doing a config backup, then uninstalling Opus is certainly worth a try. Try before restoring the config backup, in case the issue is triggered by configuration changes, scripts, etc. that have been installed. Be sure to reboot when prompted, to make sure all components are properly removed/replaced. Your existing certificate should work. Use Settings > Backup & Restore to make the config backup.

Okay. When I get a chance, I will try all that.

Leo,

Disabling the load of Ultramon and WindowManager had not impact.
