Whenever a VM guest goes full screen, the MSN messenger's status will be changed to "Busy". This could be nice if MSN's original status was Online, but potentially disastrous when it was "Appear Offline". I mean, when I'm hiding from everyone in my contact list, I certainly would want to stay that way no matter what I'm doing, including starting a VM. Is anybody else also annoyed by this? Hopefully this would change in future releases.
