in the screenshot above, please draw your attention to the bottom-right, in particular the lock/leave buttons.

You see there is no transparency or shading like there is on the rest of the 'taskbar'
i have tried disabling transparency on the taskbar, changing the colours all sorts but it stays grey and spoils the look of the taskbar

i have removed and re-added the buttons but still stays grey.
i have suse10.3 on another computer and when i play with transparency the lock/leave button background changes

any ideas anyone please?
