When it "is" us it tends to explode exponentially.. There'd be a _lot_ more noise on the forums if there were wide spread reproducible problems with any part of our products. I acknowledge that there are definitely rare cases where an individual users machine just will not want to play ball, when these things happen we are forced to go by the numbers. If the problem is widely reported then it is very likely us and receives immediate time and resources to resolve. If the problem is not widely reported then it is usually some kind of misconfiguration on the target machine. This may be X-Plane, the OS or the hardware itself. It can and does happen, but it's very very rare. At this time I feel it is fair to say that your reported issues fall into the latter camp, they are not widely reported. We have very few error reports about anything. Those that are "open" are usually VRAM-squeeze related and can be resolved by tuning on the side of caution. Thanks for your understanding. I'm sorry if I'm overly defensive but these things can explode into unsubstantiated rumor very quickly. Cheers. Ben.
