I am chasing why my FS9 crashes to desktop whenever I switch on AI traffic. After having tested all the files individually and finding that the crash only occurs when there's "too much" AI, I had the idea to check on my system config.Now here's what I found: in Windows, I went to "Programs-Accesories-System tools-System information". There it says "TOtal real memory: 1,024 MB", but "Available real memory: 546.10 MB". Does that mean that I only have 546 MB or RAM instead of the 1,024 MB that I bought?I have no great clue about hardware issues, but maybe someone can give me a hint whether I am on to a potential source of trouble here.Thanks!Chris
