Hi,I just noticed after installation of RCv4.3 that the interface is missing the "Rebuild runways button".What's the issue?

Lower right in the Utilities section.It is important also that makerwys.exe, in your main FS folder be updated to version 4.41 or better.See the update links for that and FSUIPC pinned in the top section of this forum. The current versions are updated from what was placed in the RC4 installer in case you are a new user. If on install the update ran, then update makerwys and rerun the scenery rebuild, always from within RC and if on VISTA and Win 7 RC should be started with a shortcut with its advanced property set to run as an administrator. Finally the RC installer must have been run with admin privileges.Finally be sure you you enter the correct path to the FS folder you are using each time. I keep that rather lengthy path in a desktop text file so I can call it up and paste it in each time.
