I second this, many many people are coming to XP11 and the first thing they ask in the forums is: where do I find a good B737? I would easily tell them to get IXEG if it had no major issues with the new version of the sim, but now the best you can grab is the awesome zibo's mod. Fixing a few things with xp11 compatibility would be an immense commercial opportunity in my view (even better than releasing a full v1.1 for xp10).. But anyway let's devs make their choices and cope with the problems they are having since real life is definitely more important, good luck.
