Got a new PC for FSX, when the FSX starts up I get a compatibility problem message about something in the FSX.The Windows Visual Basic will be used.I am new to FSX and the Windows 7 Home edition 64 bts.I installed the Sp 1 & 2 updates, in add/remove programme it states that I have FSX & SDK. I did a full install.Have not updated the SDK. Has this something to do with it?

It's normal - FSX doesn't get along with the Windows Aero display and resets it to the basic display while it runs. When FSX exits, the Aero display resumes.DJ

To add to ubersu's comments, you may want to consider stopping it before starting FSX, especially if you need to switch back and forth between screens. Aero is a huge resource hog.
