Try disabling Catalyst AI.

Hi Bob, Thanks for the reply. I am flying En-Route Greece(LGAV) at mo on vatsim. As soon as I land I will be trying that and reporting backRegardsDavid

>Try disabling Catalyst AI.Thanks, this helped me, so far no CTD's anymore.Regards, Marcel

Bob,It works a treat!!!!!!!!.Thanks very much for your input.RegardsDavid:-)

I have been searching every where for a fix. I even have a support call in with ATI on this one.Will certainly give this a try after this flight and hopefully this will resolve my issue as well.Keeping my fingers crossed!

I thought I should chime in too...I have this problem with the Eaglesoft CJ1 for Fsx. I am runing Vista 32.I hope the new drivers show improvement.

Thanks, just found this advise on Phil Taylor#s Blog.So far it looks good (haven't had time for a long test though)

Hi,I have been using now for a couple of days with AI disabled and have had no problems at all.David
