I've been using ASV6 since its release with no problems until now. Here's what's going on:I start the sim (I run in windowed mode) and then minimize it. I then launch ASV6 and load my route. When it all initializes and finishes updating, I minimize it and restore the sim. Everything seems to be working fine for the entire flight. When the flight is over, I exit the sim but when I try to close ASV6, it says "Program Not Responding" and I have to click the End Now button to exit.It never did this until about two weeks ago. I've tried re-installing and re-applying the SU3 but no change. Anyone have any ideas?Thanks,....Noell

Try exiting ASV6 before exiting FS9. I've noticed the same thing, but have no problems doing the above. I think it takes a while for ASV6 to notice that FS9 is no longer running....jim

Thanks, Jim. That seems to work. The only thing I can figure is that I must have changed my shutdown sequence for some reason and that's why I hadn't seen the "Program Not Responding" error until recently.Thanks for the great customer support!..Noell

Glad to hear that works for you.And yes, it is great customer support, since I'm just a customer too! :-)...jim
