It's not NZB specific - but to clarify, it happens when I go to File \ Load NZBs, and choose multiple NZB files. They all come into a post list by default - after which, I send them to be downloaded.
Right and I'm saying if you want a successful download, you don't want to do it this way. Drag and drop, using an NZB Autoload folder or double-clicking in Windows explorer can all feed the NZBs directly to the download list. Then each one can have a unique download folder.
I'd guess most users aren't feeding NZBs using the menu. On the other hand, maybe "file load" should obey the "feed directly to download list" flag too. I'm thinking I'll go that route. Make "Load" work the same as double-click or drag and drop.
