I'm trying to resurrect my MAAM SIM R4D DC 3 as well. I know 18 years later! :) I've built a WinXP era machine, installed the plane using the disc, but can't for the life of me select either of the oval panels when the flight starts. I had this running fine back in the day, but now that FS2020 is out, I wanted to show my son just how great the R4D looked and flew. It was my favorite plane back in 2002. We've tried everything to get the panels to work, but still no luck. :( I'm waiting for someone to come out with a visually stunning DC-3 for FS2020. Of course, 2020 blows away any of the previous sims, but did want to play with the R4D again - even if on outdated software.
