Hi Peter,
Ok this makes much more sence for me thank you
I think i know what your problem is i have the same problem with mine when i look to the mcdu input and have on that same computer SA-WXR running ( what by the way doesnt work...) On the moment that i have activate the SA-wxs window i cant use my MCDU and i have a hardware version so the keyinput will not send it to the software. I need to make the MCDU screen active to get it working. ( the SA-wxs works still than because it gets input from the NETDIR folder)
I dont build a boeing so i am not familair with the Eicas of PM but i assum it will work in the same way as the rest and needs to be active when you want to change screens. ( That is the nice part of the AST airbus software it will not having that problem)
I know in the past that i also used the ECAM (same as your EICAS)of PM but i had it installed on a second comp so i didnt had that problem.
So far i know you right you cant send a offset key to a certain window yet when you use more screens on 1 PC.
I dont know if it is possible to change the MCDU to the 3 pc where you have the pfd/nd running? I assum that the pdf/nd gets the input from your MCP... i only dont know if it will show the same problem like you would have now.
Otherwise i think there is nothing else at this moment than to think about computer NR.4
I will see enrico of PM next saterday and i will ask him the question as well and see if he maybe have a solution for this problem.
gr.
