Hi,
with the new 3.1 version my Grinder plugin doesn't work really well: when I load an audio file in Grinder it makes me choose it several times, I have to go pick the samples I want 2 or even 3 times in a row sometimes to finally get it, pretty weird and annoying.
The issue also been reported by other users from the KVR forums: http://www.kvraudio.com/forum/viewtopic.php?t=330288
