Download "Gamebooster" it will clear out all the Crapola and defrag memory readying your machine for FSX. Just Google it to locate download sites.

Adam, glad to hear it's better: it is almost certainly a West Yorkshire fix :) You know what they say: you never have to ask a Yorkshireman where he's from - cos he's already told you! :)

Ha ha top quote, Paul. "If tha' eva does owt for nowt, do it for thissen" - definately not true on Avsim :( John, thanks for the recommendation - I've downloaded Gamebooster and I'm going to give it a go. Cheers, Adam.

Well, I knew it was too good to be true.Just doing a quick flight from KSFO to KLAX. I near KLAX and I go to the FSPX menu and the cursor begins to rotate in Windows 7 fashion. I know this is never a good sign in FSX.True to its word, it crashed to desktop with a 'fatal error'. What an absolutely frustrating end to a trouble free flight (except for a family of passengers who apparently contracted a stomach bug and spewed up causing a mess!). So I've yet to complete a flight using FSPX.I reckon I'm going to have to have a good look on their forums.Ada

Hey guys. I don't know if anyone came up with a fix for this problem but I had the same issue with OB sound card... I changed to USB soundblaster and it runs absolutely fine now, has no impact whatsoever on FPS now. Hope this helps!
