I really like the new Learjet in P3DV4. One thing I noticed, is that when I use the mouse scroll wheel to change the autopilot heading bug, for me, it scrolls in the wrong direction. I've searched the forums and didn't find any reference to this...

Does anyone know, either with settings or programmatically, how to change the mouse scroll direction for the autopilot heading bug?

I can confirm this. Just bought it 2 days ago from simmarket so it's the latest download. In addition to the hdg bug, the course knob, altimeter setting knob and radio altimeter knob all rotate opposite of every other a/c I have flown (mouse wheel forward reduces value not increases as normally would).

I am using windows 7 pro and P3D ver 3.4.18.19475

Slightly OT, so far after 5-6 flights I've yet to hear any audible warnings including test functions. Normal? And along those lines, they advertise a fantastic 3 phase gear down wind noise which varies with changing airspeed but frankly I don't hear ANY wind noise from the gear... 

I would like to see this fixed as well.  This was the same behavior in the original version and never addressed, although being reported to the developer.  Additionally, the 2D Autopilot pop-up VS wheel direction is reversed.  I mean, it's not like a deal-breaker, but it's just frustrating.

Great job in updating one of my all-time favorite planes but why not apply a bit of polish to a great aircraft? 

Should be a relatively simple fix for the developer...
