We are using Apple Remote Desktop (ARD) 3.5.2. on 10.6.8 to ARD control remote 10.7.5 Lion machines.
When the remote Lion machine is in its "inactive" stand and at the "Login Window", the result when controlling the remote computer is a completely black screen. This happens with both ARD versions 3.6.1 and 3.6.2
Only when the time updates, that tiny upper right rectangle of the screen is refreshed and correctly filled with time display. 
A workaround that refreshes a part of the screen, is to hover the pointer over the center of the screen to screen to refresh the part where login items appear.
Is there a workaround that refreshes the whole screen with less hassle, or even better how to fix?
