OLC participation and "red marks"

Apparently SeeYou has the same workaround implemented. You need to
download a xip file with the patches and replace the files in your
SeeYou directory:

http://www.naviter.si/dload/seeyou-cai-dos.zip

1. Extract both files from the ZIP to your SeeYou folder
2. Replace your existing SeeYou.exe

You should be able to claim flights normally once the patches are
applied.

Hopefully this will clear up the problems with the Cambridge 10/20/25
loggers and OLC. Please post your experiences with either program and
the older Cambridge loggers.
