I have the same problem with my EICAS left seat. I have the downloaded version. I just reload the aircraft a second time and it will load correctly and work. No explanation why the first officer right side works and the left will not. No combination seems to make the left side work the first time.
Another problem. in 2d panel when i switch panel views (with keyboard "W") i can see the default MS mini-panel for a split second only. Shouldn't I beable to have it as well as a blank screen? texerrn
