In another reply to a question like this, I said I have not experienced this in FSX. That has not changed. However, I did say that I had  experienced it in FS9 (FS2004) at Melbourne, Moorabbin - YMMB. I don't know what the cause of it is.

Where (what airport/gate) is this happening? If I start a flight there I can see if it happens to me too.
