Hi Soulaymen,

This is because you have your monitors setup in the wrong order in your windows settings. Windows enumerates your monitors, which can be seen in the displays settings. Make sure that your leftmost monitor have id 1 and the one to the right have id 2. (Note that this have nothing to do with which monitor is set to be primary or secondary, it is quite possible to make monitor 2 the primary monitor.).

I suspect that if you open the display settings you will currently have something that looks like this (Note the numbers on the displays and their location):

You will need to change this so the numbers are in order left to right.
