There seems to be a bug in xtherion graphics editor revealed if you manage to enter a non-power-of-two zoom level.
If you get into this state then the background image and the lines drawn on top of it go out of registration.
This bug has been around ever since mouse wheel zooming was introduced. An attempt was made to fix it I recall, but it did not have the desired effect. It manifests for bitmap background images, but not for xvi 'images'.
Aha - this would explain why most of us had not noticed it before. People using a pockettopo->topparser->xtherion workflow would never notice this (no jpegs/gifs/pngs). Wookey -- Principal hats: Linaro, Debian, Wookware, ARM http://wookware.org/
