Sometimes when I double click on the FS9 Icon I get the followingerror message."Your computer does not have enough memory available to run Flight Simulator. The program will now quit."Then thing is this doesn't always happen and if I keep on clickingon the icon it eventually fires up OK. However sometimes alsoI get error messages telling me I don't have authority to write filesto FS9 or something to that effect.Would welcome any pointers on how to solve this annoying error messages. It goes without saying that I have plenty of RAMand that there is hardly any CPU activity, etc.RegardsJoaquin

Which version of Windows are you using? Try doing a disk cleanup and disk defrag. Also, if you are using WinXP, try to do a clean boot. Also try logging in using the username administrator.
