Does anyone know how to delete jobs in the queue without opening Onyx?

I put a job in Onyx that it apparently hates, and it opens up, but won't let me do anything but force close it, and do it all over again. I'm trying to figure out how I can go into a file folder and delete the file that's hanging it up, but I've looked through all the onyx folders and can't find anything. I don't care what I lose as far as jobs that I've already printed, or what's there waiting to print, but I've got to figure out how to get them out of there so it doesn't just lock up when it opens.

It's being a giant CPU/Memory hog too, so I know it's just freaking out about something.

 

That last video appears to have made it happen. Thank you for sharing that!
