--- Comment #3 from M motya_k@yahoo.ca 2010-06-02 10:20:42 --- It's the same in rc-1 and rc-2. I can't show you the screen shot, because when I take it, the black square cursor doesn't appear in it.(there's no mouse cursor in the shot at all) To reproduce, just open the EndNote X1 and move the mouse to the main window pane where all the references are displayed. The mouse cursor turns into back square when you move into that portion of the screen.
This bug has appeared after I have upgraded to 1.2-rc1
