There is one thing that's really puzzling. I noticed that some graphs (all having the same settings of layer size and font size) after inserting (ctrl+C) in Word have different size of fonts, though they have the same dimensions in Word.
I attach a printscreen of a document. Why the 40pt size font in one graph differs from the same 40pt font? In layer->display->Scale elements fixed factor is 1 for both of graphs.
