OK...just had it happen again. I realize that my lame DSL connection is to blame...most especially during weekday work hours. This time I was in fullscreen and the entire screen went black. Had my cursor and nothing else. Did the CTRL-ALT-DEL thing and there was a message from MyAAS saying it could not connect. I was using online mode at the time. I clicked OK and got another message stating that recording of time had stopped. Clicked something on that window and then...the infamous "Flight simulator has experienced a problem...blah, blah, blah" message and my flight was toast.
Which came (died) first...the chicken or the egg??
Until I get my connectivity issues solved I think I'll leave the MyAAS "online" mode off. What's funny is I had no problem getting my 15 minute weather? That really doesn't mean anything though...I might have been in between RW weather updates when it all went to heck.
