Whenever I start FSX it shows the FSX Loading Window which is in the center of the desktop (so far so good). Then after its finished loading the FSX window appears into the bottom right hand corner. It shows its on a blank page instead of Free Flight. I'm able to switch to another page on the left hand menu but after I switch to another page all the other options on the left hand menu disappear and I'm stuck on that page.Any help would be appreciated thanks :)

I have just started having the very same problem only it pops up into the normal position in the middle of the screen after a few seconds so all is well. On other occasions where things don't look right I have clickd on the alt-tab buttons and it has reset back to the right position, like when the ATC window does not have the reply text showing and you can not answer the ATC request. Hope this helps some...fisheye

That originally happened to me and now its just stays in the right corner. I haven't been able to play FSX for weeks and I'm not sure what to do :(

Delete fsx.cfg and reload sim. See if that helps.

That partly fixed the problem but now when I click free flight the loading ring appears then shortly after it stops responding.EDIT: I'm gonna take a guess its bitdefender that may be blocking the aircraft from loading. Otherwise i'm still stuck :(

Do you have F1 Sound Environment + FSDreamteam installed? I got related problems due to dll.xml conflict with the addon manager entry which should be on the first position.
