I use Windows 7. I have a project open and a file from that project. I want to split the window using Window->Split to edit one part of the document while seeing another one. The split option is shaded (as in non-clickable). Any idea why?
Also, when I have many windows open the buttons Tile Horizontally and Tile Vertically do nothing. Any idea of what I'm doing wrong?






Given that the window environment is usually controlled by Windows libraries I start to suspect it might just be a bug, but I thought I would give it a try here before bugging the developers, in case it isn't a bug.
