Alabeo has released the V4 version, and since we do not have a GTN750 to go in it, we are stuck with its GNS530 for a while.

I've fixed it up a bit, so that the knobs operate nicely with the mouse wheel, and I have turned off the Airspace messages.

Also included are my autopilot fixes.

Let me know via PM (include your email) if you would like a replacement panel folder.

Bert, with the recent release of the GTN 750 for P3Dv4, I was just wondering if the GTN popup function is working for you on this plane. I find that with or without your AP mods installed, there is no way to popup the GTN by clicking on its screen or bezel. I must use a key command. 

I followed what I think to be the proper setup procedure, which is to run the exe which modifies the panel to include the GTN 750.

BTW, I have the same issue with the Shrike.

Thanks, Robert

Problem solved. I'd forgotten where the popup button click spot was for both of these planes. For anyone who makes the same mistake, it's at the center of the top bezel, not on the main window as indicated in the Read Me file.
