This morning (14Mar2011) I installed the latest version of Defraggler.
With previous versions, while Defraggler was working, I could minimize and continue on to other sites as Defraggler worked in the background.
Not so with this version . . . none of my browsers work (IE9, mozilla firefox, google chrome).
In fact, when I try to use a browser, the computer freezes.
My OS is Windows Vista Home Premium.
Help!
