[V8i]After install extra lines appearing on view

I have just had my computer rebuilt and Microstation reinstalled.

I don't think it has been installed correctly as extra lines are displayed on the view.

I'm not an expert user and mainly use Microstation to view files.

It happens with all files so I'm sure it is a setting that needs changing. 

Attached is a DWG file viewed in AutoCAD and viewed in Microstation - the differences are obvious. There also appears to be a camera.

How can I get the file to view correctly.
