Hi all!Only a brief question about bugs fixed by SP1: I don't understand if "terrain.cfg" modified is also necessary for FSX after installing SP1 or is included in this update ??Thanks all for replay!Max

Hello,I did not know if necessary, I installed it and it seams OK. No problems.

Max,SP1 fixes some of the river anomalies, such as the River Thames in London and quite a few others, but not all of them. I added the modified terrain.cfg fix to SP1 and "fixed" the Ohio River problem I had in my hometown with no apparent ill effects on anything noticeable. I suggest, if you haven't already, go ahead and put it back in. Be sure to rename your original terrain.cfg file as a backup first!
