I've build a new onboad computer. With the new configuaration I've connected my screen via usb3 "display link" to the main unit. Now I can start expedition 4d via Microsoft Remote Desktop Connection RDC and everything works perfect. Even when I switch back to local control everything works as expected. But if I start expedition local it immediate crashes as soon a c-map chart is opened. Other charts work fine. A direct attached display works fine. Any ideas?
