Hi Mitch, I am glad you found your problems;http://forums.avsim.net/dcboard.php?az=sho...id=218057&page=Remember active supports forum is here ThanksChris Willis[link:fsw.simflight.com/FSWMenuFsSim.html]Clouds And Addons For MsFs

Hi Chris!Yes, it turned out to be a LAND CLASS .bgl in my ADDON folder that had a TEXTURE (the no-no) folder also with it.I took that *****land class***.bgl file out of there and placed it in its OWN folder with NO Texture folder created. I then ran FS9 and it stabilized in memory hogging at around 650 MB. Can anyone actually explain WHY a landclass in the ADDON TEXTURE folder acts as a memory timebomb?!?!?I had no idea about that issue!Cheers!Mitch R.

It's a FS04 bug.Hope this helps,JimActiveSky Supporthttp://www.hifisim.com/images/as2004proudsupporter.jpg
