Why doesn't this work?

I'm sure it's something simple, my brain is on holidays.

It seems resetting the 3d Graphics mode kills the entity?

//////////////

Graphics3D 1024,768,32,2

Stop

ttt=LoadMesh( "AnyMesh.b3d" )
EntityCloseStatic = CopyEntity( ttt )

Graphics3D 1024,768,32,2 ;windowed

PositionEntity EntityCloseStatic, 10.0, 10.0, 10.0

setting the graphics mode deletes all graphics and meshes, this is normal directx behaviour.
