In Windows 8.1 Update 1, if you have multiple monitors, you may have observed a strange behavior of the mouse pointer. When you try to move the mouse pointer across to the other monitor, it sticks at the edge of the screen. If you move the mouse pointer fast, it goes over successfully to the other display. This is a not a bug, it's a feature. Let's see how to fix it.
Windows 10 users, please refer to the following article: MouseMonitorEscapeSpeed (Mouse pointer stickiness) fix for Windows 10
The problem I described above of mouse pointer stickiness can be best described by this video:

This sticking of the mouse cursor on the right edge of monitor 1 and the left edge of monitor 2 (shared edge) is a feature to make the charms bar and scroll bars easier to use. Luckily you can disable it.
- Open Registry Editor (see how)
- Go to the following key:
Tip: You can access any desired Registry key with one click.
- Look for a DWORD value called MouseMonitorEscapeSpeed. If that value does not exist, then create it. Change its value data to 1.
- Repeat steps #2 and #3 for the following Registry key too
- Now restart the Explorer.exe shell or restart Windows.
That's it. This should disable the multiple monitor mouse stickiness on the shared edge.
