Scrollbar Blindness
I also have this issue with the disappearing window borders.<p>I remember on IRIX they were so bold, a real tool to be used. Same on Windows up to and including Windows 7. Now it's like you have a 2 pixel wide invisible border, hard to click, which may be the shadow of the window, or at the edge in the window; it's hard, specially when working over VNC. Nothing is gained by freeing up those 10 horizontal and vertical pixels.
