This is my first message and my first try of Inkscape.
I am wondering about the small but visible visual misalignment between the grid and the rulers. In the following image I have my default units (hence the rulers) set to cm and the grid origin is (0,0).

The improper alignment varies with the zoom: in some zooms it looks properly; in others it does not.
I am using Inkscape 0.45 under Ubuntu 7.10.
Thank you,
Evgeny
