After the latest update, at first Amibench wouldn't load - it got stuck on a grey WB screen
So I restored everything to the inbuilt defaults, replacing everything
Now, Amibench kind of loads, but icons on the desktop and on the dock are all garbled, and when I move the mouse cursor over an (garbled) icon, for example Work or what else is on the desktop, Amibench immediately crashes back to A600GS menu
Sorry your havng trouble.
When you restored to inbuilt defaults did you choose to REPLACE the current install or MERGE with it?
Please try with REPLACE , then assuming tat works try going to the advanced updates panel and reinstall the latest components.
