Black background for lock screen on Lion OSX

[MrKaji]

Hi guys,

Just wondering if any of you guys are getting a black background when your in the lock screen?

Is this a bug on the MBA 2011 Lion OSX?

Thanks

It happens to me every now and then when I open my 11" MBA 2010... Usually if I close it and reopen it I am taken to my lockscreen. Once maybe twice I have had to hold down power then reboot.
