I just installed ver 6, too, and am impressed at the improvements in the menus. I'm very excited to fly it soon in some IFR training. I did notice one transient error message as the update installed: it was something about not locating a .dll file, but the message cleared itself, and the update did finish. Did anyone else notice that? Nice job, guys! Next step: pick the best ADS-B receiver to use with it. Feedback?
