Thanks Matador. I will explain.
I have changed the icon settings for the docked app in WindowMaker and saved my changes on exit out of WindowMaker and xf86.
When I reboot into WindowMaker everythings looks perfect and my icons look perfect!
However when I open an appliation, then the relevant docked app icon changes to the original icon picture setting.
For example, I have the nice crystal icon for my konqueror browser docked app in WindowMaker and it looks sweet. When I open Konqueror, the icon in the dock reverts back to the original dodgy icon
. Then when I close the application, the icon reverts back to the nice crystal icon.
Hope this is clear. Thanks. Not a major problem, but would nice to clear-up.
