I'm certain that Anvil has some unlit candles
And I am certain that there is something somewhere too. However, as we've kept telling you, we can't fix stuff unless you're specific about what needs fixing.
How do i remove the nuclear dawn effect when in interiors on day? If i removed the sky when interiors then i wouldn't get the day/night lighting effects that real lights gave in the old version right? Or was it real lights?
Have you already fixed the window problem?
Did you try the oblivion.ini tweaks Gekko linked to? There's not much you can do besides reporting bugs and waiting for new releases - if you report the bugs, we will do our best to fix them, but you still won't get the fixes until they're ready to be released. For instance, I've been sitting on fixes for various weather bugs for weeks now, because they aren't really complete, and I need feedback on some of the SI bugs from Brumbek, who has been absent for a while now. That, and RL just got a bit busy, so I don't have much time to do stuff anyway.
