LibreOffice v4.0.3.3 Calc when text is highlighted, will hang once Control C is pressed to copy the text. It takes several seconds before the cursor will move to a different location and then paste the text. I have never had this problem before. What can I do to get back to simply selecting text, Control C and then instantly moving cursor and pasting text?
