HiReporting my problems:Flight: Faro (lpfr) to Lisbon (lppt), Dark&Cold startup.1- Sometimes on approach to an airport, few seconds after a change speed in FMC Legs Page, fsx disappear.I get the message "your computer has run out of available memory. Please restart FSX....." once.2- It happens the same (I'm in dual monitor)when I move a spot view window from one monitor to another (no error messages).3- The 747-400 can't be selected when I try to change fsx settings and then save it(I have to select another aircraft before changes).After all the above occurrences the fsx doesn't restart again, PC needs to be rebooted to solve the problem. To make a successful flight I need 2 or three reboots......Congratulations to PMDG, I believe the "Queen" will be better after few patches..Thanks.Notes:No addonsPMDG FSX settingsdll.xml okfsx.cfg ok2GB memowin XPmotherboard asus 3.2GHz P4RADEON X1900 - 512 Mb

HiThings are going better now, after overwriting the file in c:Documents and SettingsApplication DataMicrosoftFSXfsx(not the fsx.CFG) by a fsx original backup file created during fsx install.There is something wrong with PMDG settings and fsx settings,I think the file was corrupted but I'm not sure.Bye
