NB 6.80 Beta 9  b4978   W7x64I just wanted to let you know about a few things I've been noticing before I try b10.
Watch topics - selecting 
don't unrar doesn't always work.  I found a pre-existing watch with 
no unrar would not disable unrar after the upgrade to b9; tried making a new watch with same parameters - sometimes it works, sometimes not & sometimes it does 
some unraring.  
 Downloading nzbs - some files are bounced to 'failed' tab saying "already d/l'd" when they are in fact totally new.  This has been happening with some TV shows this week.
Merging identical file-set d/l's - previously if I have two nzbs with same files (eg in different groups, with some missing/broken) NB has merged them to prevent duplicate d/ls & creates a unified single output.  I just saw that I'd d/l'd gigs of dupes.  What's  annoying was once I realized that this was occurring I paused & selected 'pause' on blocks of files that had already been leeched - so that only non-dupes would be grabbed afterwards.  
NB then decided it would d/l them all anyway.
Weird, as NB had stopped, leaving only the paused files in the queue.  I'd manually merged the folders, manually ran the par & it was all OK.  
But I'd begun a header d/l while doing this.  NB started leeching the paused dupe files as well.  Took me a while realize this...  

So it looks like for some reason the dupe detection is not 100% for me, amongst other things.
Hopefully b10 will have addressed all this
