clean up MiniB3D - memory leak?

Hi,

i have serious problems to clean up the memory.
i need to call Graphics3D in different resolutions as an dll function.

here is a simplyfied example:

----------------------------------------------------------------------

Import "minib3d.bmx"
Framework brl.blitz

Repeat
Init_3D()
DebugLog "mem " + GCMemAlloced()
key = WaitKey()
Until key = KEY_ESCAPE


Function Init_3D()
Graphics3D(400,300,32,2)
Local cam = CreateCamera()
Local cube = CreateCube()
PositionEntity cam,0,1,-4
PointEntity cam, cube
RenderWorld()
Flip
FreeEntity cam
FreeEntity cube
End Function

----------------------------------------------------------------------

i used FreeEntity to clean my 3D World, but the memory is still increasing after each call. Any Ideas?

Thanks

Stephan
