Sorensen (jessorensen) Date: 2010-07-01 21:55 Message: Hi, Thanks for getting back to me - glad it is working for you now. Closing Jes ---------------------------------------------------------------------- Comment By: Shawn starr (sh0nx) Date: 2010-07-01 20:01 Message: Oh yeah, this is old. You can close it. I am sure it has been fixed. I certainly don't notice it anymore. ---------------------------------------------------------------------- Comment By: Jes Sorensen (jessorensen) Date: 2010-07-01 09:58 Message: Hi, This was with quite an old version of KVM, it's likely been fixed by more recent updates. Are you still seeing this problem or can we close the bug? Sorry nobody got back to you before, I am trying to follow up on lost bugs now.
