found a problem when solving customers problem that they do not learn to press the update/save icon on an editgridview form, because they do not know it as a “SAVE” button. So I wanted to change that button style to a style like “insert” “update” etc.
trying to change that by using Main Menu->Tools->Layout->Buttons
-> Copy -> Save brings me to a list of the button without any button to edit. I only can choose new.
Switching back to a preinstalled layout does not change that, even the preinstalled buttons are not shown anymore.
P.S.: after a server restart, all images still gone
