Examples: [1] I selected a range of cells recently, by clicking and dragging, and when I let go of the mouse button, all of the selected cells shifted up and to the right by one cell, and CTRL-Z didn't undo it! [2] I have a workbook and when i duplicate a sheet with a chart, the chart is blank, so i have to delete it and re-insert a new one. [3] Sometimes the left-hand X-axis is cut in half, and I have no idea why, but if I create a new doc it goes away. I really, really want to promote LO, but it is very buggy. I can deal with it but I don't think others would.
