Transparency in all display modes

Good Afternoon,

I know this is probably easily fixable but all of my Poly-surfaces and closed polysurfaces are transparent when unselected. This means that the edge geometries in the background are visible even though it looks shaded. If I explode it and select a single surface it then becomes visible

any help would be greatly appreciated as I just cannot work with the program like this

Could you post your OpenGL settings?
Do you have any objects that are far away from the origin?
Does running RebuildMesh make a difference? or RefreshShade?
Can you post a file?

Do you have an AMD graphics card? This might be your problem… --Mitch
