Windows calibration is retained when Windows is rebooted; AH calibration is lost when Windows is rebooted.
I am running Norton Internet Security, latest version. I will pay closer attention to the files in the Settings folder. However, I wouldn't think that NIS would allow these files to be updated during a Windows session, but then restore them to previous values on reboot. I mean they could do that, but why? Seems unlikely. After all, there are many other files which the game changes (views, etc.) which retain their settings through an XP reboot. Why just the issue with controller settings?
What's the file (name) which contains the CH joystick and CH pedal settings?

So finaly the joystick brand.
Yes I would have asked you if you are running the CH Manager app and first calibrating in windows. Bentnail was talking the CH support and they recomend running the CH Control Center and checking start in Mapped mode even if you are not using any profiles. Also run the CH Manager and calibrate in windows.
If it's the game only that you loose calibration every time delete your current (chfighterstickusb.jsm) and (chprothrottleusb.jsm) and let the game generate new ones. Check their attributes and make sure Read-only is not checked on your (jsm) files. Or if you are ambitious rename the current Settings folder to (Settings.Old) then make a new folder (Settings) and start the game so it will rebuild the files and subfolder. Then run the game and calibrate your joystick. Exit the game, restart and see if the calibration holds.
Before you delete your (jsm) files copy the contents to a (txt) file. If the deletion of these files fixes this issue you can then copy the saved contents from the (txt) file back into your new (jsm) file.
When I was on XP I had to do that a few times. When the game started doing things like this more often I would completely uninstall the game and perform a fresh install after running a defrag of that volume. I backed up the Settings folder so I wouldn't loose my setups. Properties on harddrives will change over time from many sources.
How applications lay down and interact with files can be interfered with by those same sources.
I run ESET 5 which has a gameing mode that completely shuts down all the antivirus properties when AH goes into full window mode. I set the HTC folder tree to excluded for good measure. BofA ran Enterprise level Norton and occasionaly files were corrupted or their nature changed on the 3000 or so servers I babysitted. Norton is a money making scam of a virus in itself but, BofA's underwriter specified using it to keep the SEC happy.
Have you recently changed, updated your antivirus engine or added anything new to your OS that enumerates the contents of your harddrive as part of it's function?
As I stated before, if there was a simple answer Skuzzy would have given it to you already. Have you simply scrubbed the game from your hardrive and reinstalled a clean version?
