I have several drawings created with Autocad 2009 which show this behaviour. The A3 layout sheet has one entity on it - the viewport, all other geometry is in model space.
On importing the layout into Impression 2, a number of model-space entities (lines, polylines etc) extend beyond the right hand edge of the viewport, while on the other 3 sides the entities are clipped correctly.
As this user had not updated to Impression 3, we tried upgrading and found that Impression 3 did exactly the same thing.
Impression is running here on Vista x64 Ultimate. I gather that 64-bit OS's are not officially supported. I have not tested it on a 32-bit system to see if it is related.

I have attached 338#sk6.dwg which contains the layout sheet we are trying to import (sk6).
A screenshot of the problem can be seen here: http://www.balston.co.uk/kp/impressionscreenshot.p
Many thanks for your help
