Hi Ian, I realised (soon afterwards) that if the kbd assignments were missing in the PMDG menu then it would not recognise any inputs so, through desperation, I copied the attached .ini kbd file into the PMDG folder again, in order to enter the assignments into PMDG.

I did, however, copy the PMDG folder as a backup, as it was a gamble, I know. However, this time it worked and as far as I know all inputs are working fine. I have not checked all inputs yet though as I have'nt had time to program the FMC.

I need to check the LNAV / no heading selection quirk though. I hope I do not have that problem. As far as I know you no longer have that quirk now? I will check back in the next 24 hours, hopefully, with good news that all inputs are correct.

Thankyou so much for your help so far Ian. Appreciated.
