For some reason whenever I quit playing civ conquests my desktop goes from 32 bit color to 8 bit. This happens everytime I close out of the game. Easily fixed, but annoying. I have a GeforceMX4000 with the latest drivers. Does anyone know how to fix this or have any suggestions?

I don't know anything that will definitely fix it, but you could try some of the ini settings (although they are aimed more at resolution than colour depth). There is a list of them available in this (http://forums.civfanatics.com/showpost.php?p=1980093&postcount=781) post. The Video mode & KeepRes are probably the best.
