When a download (nzb) failes, then pause, go to next

[nbwul62]

I loaded 2 .nzb files, the first one failed and Newsbin continued reporting that parts are missing (or something like that).
I paused the download and removed it (in the downloading files section).
After that NB went on to download the 2nd one successfully.

Would it not be an idea that, once NB encounters such download errors, it automatically stops trying after -say 5-10 seconds- and then continues with any other download in queue ?

Thanks.
