This has always been a thing, but I wondered if there is a fix because it does get annoying.
Whenever Newsbin runs out of space, it pops up the normal window showing its out of space and cannot continue downloading. You can't pause or anything because you can't get rid of that window. It just pops right back up if you close it, blocking you from the rest of the application.
So, you go to your drive and manually delete a few large things to clear some space. The moment you that, the popup vanishes and Newsbin goes into a seizure for some time. It becomes unresponsive and the title bar flashes rapidly (enough to turn the monitor off or cover it with another application window so you don't have to look at it as it hurts the eyes).
Sometimes it will sit there for many minutes flashing until it feels it is happy about something.
It's a powerful 4K-editing system with 64GB of memory and doesn't lack anywhere else, and Newsbin has always done this. So it has to be something with how it handles coming out of a state of not having any capacity left to save to.
