I am running Windows 7 on my Macbook. Normally in Windows on a PC if you open a windows explorer window you can place the cursor at the top of the window and drag to edge of screen until cursor reaches the edge and the window then automatically fills half the screen from that edge. You then do the same with another window to the other edge. You then have two nicely apportioned windows to move files, copy etc.. This doesn't work in Parallels 9. David C
Thanks very much. I changed to full screen and it now seems to work whether I am in full screen or not.
