I'm also having a problem with auto unrar. It used to work fine but hasn't worked in the last few versions I've tried. It's starting to get annoying. It is all downloads, whether they need repairing or not.
Auto Unrar is enabled, the small par2 file is not imported as paused, and par2 checking is enabled.
There are no new downloads under the par2 tab though, just three old ones, from a few months ago. Of those, two have ticks over the winrar logo, one does not.
Anything I can try to remedy the situation?
