I believe that I've fixed the window flicker problem. http://www.4shared.com/file/253404130/bd0770da/WindowLightingSystem.html I'd appreciate any feedback in case I accidentally messed something up that I shouldn't have, but cursory testing by Arthmoor and myself indicate that it's solid

Could you explain what you did exactly? I mean I know the principle of my advanced plugin (script) which is:
-no light during the day but when it rains (which is checked with the constant IsRaining from the game) which is then treated as the lighting on every (75%) building but with a paler color.
-light all the night long for some buildings (inns mostly), including the cathedrals.
-light on 75% (or 80%) of the building. The check is being made for each architecture mesh each time you cross a game cell border. Each time a house with windows passes through the script, there is 75% chances that the windows will lit.
The only flickering I have been able to witness is either due to people crossing cells borders over and over again, or a problem with the saved game and the script which is fixed by just disabling the plugin, enter the game and wait a bit, save the game, exit and re-enable the plugin before playing again. For the rest, the plugin works as advertised.
I just want to know what are the principle you use in case everyone find it more efficient and you give me the authorization to replace my advanced one with yours for a next release.
