This problem is caused by a feature of Unity related to edge stop velocity: Have a look at CompizConfig Settings Manager (might need to install from software center), under Ubuntu Unity Plugin > Experimental there's an option called edge stop velocity, I think that may be what your looking for or one of the options above it. Based on other people's postings you may find these settings work well for you: Launcher Reveal Pressure = 3 Launcher Edge Stop Overcome Pressure = 15 Pressure Decay Rate = 3 Edge Stop Velocity = 10 Cheers ...

This version of unity allows for displaying the unity launch bar on both monitors which I believe is the cause of this problem. Even if I disable the bar that is in the middle of the two screens (which I did because it looks silly) the pause still occurs. To be clear, when I say "pause", I mean that using a continuous mouse movement across the boundary, the mouse will stop for approximately 1 second at the edge of the screen before moving onto the next screen despite continuous movement. This is especially painful for moving windows across screens because it then it always tries to snap the window to the border (half screen sized).
