TP2 backlight setting is all screwed up & keeps changing

[tyhart44]

I am having this exact problem...tried the registry fix and it works for a while (just like changing the setting in Sense's settings does), but then it comes back later that day or the next day. I am not using a power management app or anything like that, and I am using SmartLock 2.0F...but I've been using that for months with no problem. Last two things I installed were Skype and the WP7 theme, which I deleted shortly after.
