When using the Posky 757-200 I find that with engines at idle (thrust handles pulled all the way back) and parking brakes engaged the aircraft still rolls very slowly forward. The parking brakesdo not hold the aircraft. Is there a way in the aircraft config fileto reduce the thrust settings at idle to help me with this problem?If so please let me know in what area of the aircraft config the settings are, and how to change them to help me get rid of this problem. The current idle settings are give me a faste than normal taxi speed and require braking every so often. I would appreciate your help.

The "creep" has always been a problem with FS9 from day 1.
