LibreOffice Calc, v. 188.8.131.52, Build ID 410m0 (Build:2) with Kubuntu 13.10 (Saucy). If a small block of cells (say, 2 columns and 20 rows) is selected, trying to move the block (either by dragging it with the mouse left button down or by using Ctrl-C/Ctrl-V copy/paste) causes the program to freeze. I can minimize it, so I can continue with other work, but can’t close or save.
Guess the next step is to uninstall and reinstall? Obviously Calc is unusable with this problem.
