Yea, I got kicked off WOLF yesterday too. I was AFK for a minute and had the message when I came back.
I also noticed related issue: a lot of times, on Alt-Tab my comp would get really slow, because DKservice.exe (Diskeeper background task) would hang it up (possibly, cause my partition with the game on it is pretty full (it’s not a system partition, but DK runs automatic background defragmentation, and I only have 10 GB out of 250 on that partition). If I kill DKservice.exe, Alt-Tab switching flies.
