I am modifying a panel for the DC-8 and have everything just right with the exception of the A/P. The A/P uses RKG_Buttons (Version 9/24/2002). I have a newer version in my gauges folder (8/24/2003) but it does not seem to have the a/t button. The problem is that the AutoThrottle does not work and I cannot manage speed. Any ideas ?I am willing to switch out the entire A/P system if necessary but again not sure how to do that so everything will work correctly. I have to think the person who made the panel originally had it working so it is just something simple that I should be able to correct.Just to check I reloaded the original panel and it does not work there either. thanks,Mark.

Well I renamed my modified panel and reinstalled the original and it now works. I guess when I edited the panel and removed some gauges it caused the problem. The question is how can you tell which gauges are linked or dependent on other gauges in the panel ?Mark.
