I have a large file I am working on. I have made a duplicate, so there are no previous versions anymore (cannot revert back to prior timestamp). However, my Activity Monitor shows Hype Thumbnail Generator consuming upto 70% CPU at times and has really slowed down the entire system. Refreshed the computer a few times too, however has not gone away.
So, what is the Thumbnail Generator and is there any way to bring this under control?
