Hi Garry
Thanks again for looking into this. About your questions:
– other apps like Indesign, Photoshop, FreeHand etc. do not show that behavior
– I have Snap-to-Grid off in the page menu, not in preferences.
– I don't use a Retina screen. But good you mention this, because I have a rather over standard display size of 30" with 2560x1600 screen resolution, but in usual 72dpi.
I will check your suggestion, looking at grid lines and their relation to the problem.
Also thanks, Winxi, for your post. Interesting you have this on Windows. I am using Scribus on Mac OS X 10.6.8.
Greetings
Thom
