Hello,
I've been reading some of the issues with Newsleech. I am having a similar problem but I am not using Newsleech. I have the Alt.Binz RSS tab configured to point to the TVNZB.COM RSS feed:
http://www.tvnzb.com/tvnzb.rss.
The issue is intermittent. I have about 15 filters configured to download TV shows. The filter list I am currently using has been in place for a number of different Alt.Binz versions and I have never had this issue until recently. About 50% of the time when Alt.Binz detects a valid post it downloads it normally as it should. The other 50% of the time the entry on the RSS tab is highlighted as if it has downloaded but the file doesn't download. Sometimes highlighting the file and CTRL+D/CTRL+P doesn't even add it as a download. After 4-5 tries (CTRL+D/CTRL+P) it will add.
If there is any further information I can provide to help resolve this let me know.
