--- Comment #1 from steveglowplunk@gmail.com --- The same problem happens to me too on Word, Powerpoint and Excel 2010. I'm using Wine 2.8 and the windows version is set to Windows XP. One workaround I found is to click the left and right mouse button at the same time (left mouse button first, then the right). Weird but it works. However, this does not work on the laptop mousepad somehow. I hope this annoying bug can be finally fixed.
