Whenever i used to go off the mains and onto battery, the taskbar (classic start on 8.1) and menus used to go opaque. i assume this meant that aeroglass was shut down for the sake of powersaving. Now, however, no matter how many transparency settings i turn off in classic start menu settings i can never turn off the main taskbar transparency!: either on AC or DC power. many thanks for any thoughts or insight on how to restore this functionality ....
