taskbar transparency

[Guest]

when i now started vista premium, the taskbar used to be transparent when it
was showing the desktop, now it isn't, it's opaque. however the transparency
is working in the other open windows and the Start menu, how can i get the
taskbar transparent again?

Reboot - then check to see Aero in running in
(The reboot may fix issue.)

Go here and on Windows Color and Appearance Screen click
"Open Classic Appearance Properties for more Color Options"

Check that Aero is Theme and then check Taskbar settings.
