I have a Windows 7 guest OS installed and attached to the domain at work that I run in coherence mode. The Windows domain policy requires that all client machines automatically lock after 10 minutes of inactivity. I cannot be excluded from that policy. The problem is that when the Windows guest OS locks, Parallels brings the "CTRL-ALT-DEL" Windows notification screen to the front, hiding anything I was working on at the time in the Mac host OS. Is there a way to tell Parallels to not show that lock screen? Failing that is there a way to prevent that lock screen from going full screen and hiding whatever I'm working on? I don't want to have to lose coherence mode, but this problem is starting to affect my productivity. Thanks.
