I downloaded and installed the excellent X-35C. It is GREAT! The plane has an autopilot in the VC which is an old FS98 gauge. It only allows the heading and course to be tuned in 10

No, you cannot "fix" the compiled .gau file. However, you can find and fix whatever gauge is triggering a "continuous event," which is the primary cause of this behavior.Alternatively, a registered copy of FSUIPC may be used to "fix" the problem by ticking off the box labeled "Fix Control Acceleration."

Hi Bill. Thanks. I am a registered owner of FSUIPC. I'll check into that setting. All my other gauges don't exhibit this problem. Best regards and Thanks, Bob.Best regards, Bob.
