Is this Dorico or my computer?

I’ve noticed on a number of occasions that after working in Dorico after I exit the program I will often have to reboot my computer in order to get back in. When I double click on the Dorico icon nothing happens, and that’s when I have to reboot. Any idea why that would be? I bought a new computer with a ton of memory in order to run Dorico, so this seems odd and frustrating.

Mac or Windows?

Do you run Dorico on Windows or a Mac? On Windows, the Dorico and audio engine processes sometimes keep running after closing the application windows. In this case you can terminate them in the task manager. Afterwards, Dorico starts normally again.

Maybe post a diagnostics report when it happens next time. Then the development team can have a look and will probably find the reason for the issue.

Look for processes called “Dorico” and “VSTAudioEngine”.

Windows

Do you have any idea what program I should look for in Task Manager?

Yes, as @asherber already mentioned, it’s Dorico5.exe and VSTAudioEngine5.exe. They appear in the Details section of the task manager.

Do you have the option enabled to show the - I don’t remember the name , but basically it’s the same window that lets you open a new project or create a new one - do you have option have it appear after you close a project? I ask because it can take a goodly while to appear in some circumstances and Dorico isn’t actually shut down until that comes up and you exit a second time,

Windows?
As others have stated, killing the VSTAudioEngine.exe process with the Task Manager will usually get you up and running again.

Ideas…

Make sure whatever power profile you use doesn’t let things like USB ports or other devices ‘go to sleep’.

What kind of audio interface? If it’s USB/Thunderbolt/Etc…
Try shutting down the system and connecting it to a different port if you can. If that seems to fix it, you could try the original port again. Give them all a try actually (just because you can). It’s good to know which, if any, noticeable changes (for the better or worse) different ports can have on your setup.

If none of that more permanently sorts out your issue, and you can, try a different cable. Post a diagnostic report (See Help in Dorico to find out how) here for the Dorico Staff to study.

If you have a PCI/PCIe audio interface, give the system a ‘true’ cold boot. As in, no power coming in at all for several seconds.

I think the main thing here with either type of interface is killing all power to the interface for a few seconds, as well as forcing the drivers to get a fresh start.

These are just ideas. In the past I’ve had some interfaces that work fine for many days in row, then little issues like this gradually creep in (Apps like Dorico not seeming to cleanly say goodby to the audio interface and shut down. I’ll still find them running processes in Task Manager). A true cold boot (cut the entire power strip and let it sit a minute) usually gets me up and running again for days, if not weeks.

No. When I can’t reload Dorico that first window with the loading options in it doesn’t appear. So, when it doesn’t appear after I shut Dorico down I know I won’t be getting back in until I reboot.

Thanks. I’ll look for that file the next time I can’t reload Dorico.

After a couple of attempts it’s actually the Dorico.exe file in the Task Manager that needs to be shut off. It’d odd that this doesn’t happen every time I click out of Dorico. About every third time.

I will add that I have noticed using Mac, that after I close Dorico, I need to wait a bit before re-starting Dorico. If I restart too quickly, the program will not load.

I have not timed this, but it probably is on the the order on 10-15 seconds.

It clearly has to do with the termination of processes.
