I am wondering whether anyone has noticed this issue in Mathcad 14 (M20): When I am doing seemingly 'normal' editing such as moving regions, cutting and pasting etc.., from time-to-time MathCAD will suddenly duplicate the region that I am editing. It will be difficult to notice because the two regions will overlap exactly. But if I try to edit or move the region it then becomes obvious. In extreme cases, MathCAD has actually duplicated almost the entire workbook, which is very difficult to resolve. Thanks.
