Are you dimensioning in paperspace? If yes, are you locking your viewports and freezing/locking the layer they are on? Do you edit the modelspace content by clicking on the MODEL tab or by double-clicking the viewport edge?
Do you use Annotative dimstyles and text styles?
Can you repeat in ALL drawings, even if you started a new one?
Do they move when you start LT/open the file, or while you are in it doing other things?
