Ok, I'll give all the information I can...if more is needed I'll get it ( not sure what else might be needed ) I am running windows 7 x64 on my 27" iMac. Everything was hunky dory until last night, for some reason my volume and other F keys do not work ( on windows only ), also the screen is as bright as it can be ( I normally have it set at its min setting ). Now I have noticed that the Boot Camp icon is now missing from...what ever you call that small box of icons in the lower right hand of the win 7 task bar. If I reinstall bootcamp from the dvd that came with my iMac everything is fixed!...until I restart windows again. I have not changed anything besides switching my anti-virus ( on windows ) to webroot. Does anyone have a possible solution? Thank you. Edit: If it matters my keyboard is the one with two batteries.
