I am not sure if this showed up after SP1 or IE9 since I pretty installed the at the same time, but towards the bottom it not says Internet Explorer, expand the + button and you get Java Script Timer Frequency.
What made me aware of this is that when I woke up this morning my laptop was shitdown and the battery was at 5%. It should have been sleeping like a baby all night like it usually does. Now I have a laptop that's been up all night and it;s going to be a bitch all day to deal with
Anyone else notice this?
