I am using PCLinuxOS2010.KDE on HP Mini 110 netbook with 1024x600 screen. I am looking to increase the usable vertical space. I have reduced the taskbar/panel height by dragging. But the icons of Lock/Logout appear big. How to set them to a smaller size?
Going through Configure Your Desktop > Common Appearance and Behaviour > Application Appearance > Icons > Customize KDE Icons > Advanced > Panel did not have any effect.

I am looking for the size of the icon on the settings page.
