Hi everyone, this happened the second time now during the last tree days but never before. While zooming there is one point where a proton axis on the right switches from two decimal places to one and therefore the white space for the axis as well as the canvas for the spectrum get adjusted. This causes a rescaling of the lower scrollbar and a full redraw of the spectrum with a short flash of white, visible when using a dark background color. Analysis locked up in this state, jumping the axis back and forth and flashing the strips in the window with full throttle on the python which needed a sigterm, no reaction to ctrl+d in the terminal. Regards Tolga
