I see! That solves the mystery :) Thank you for looking into it Michael.

And in danger of a mild thread highjack- I have been trying to find a way to map something like this-> script:moi.ui.getActiveViewport().Zoom( 0.9 ); on my mouse wheel in an attempt to mitigate the jump caused by the small scale issue we were talking about. Is by any chance any .ini setting describing what the mouse wheel scroll does inside MoI? Or a way to smuggle a Ctrl press along with it :))
