hoster lite viewers screen badly out of sync and 3 screens showing

[ddouglass]

The third screen in 3.4 would be the SND (how quickly we forget the old ways). Click the SND button to change it to red and it will close that window. Don't compare 3.4 and 4.08 for one working and one not. That is an "apples and oranges" comparison. 4.08 isn't anything like 3.4 in program code or function.
XP or Vista?
If you have done all the tweaks listed for the operating system (check it again if you have done any updates) and tried the tweaks at BlackViper to turn off unnecessary services and it is still out of sync you can try adjusting the sync timing in the Tools\Options (last item).
