Synergy 1/2 : switch coordinnates wrong

[Konorr]

Hello,

I'm having an issue with both Synergy 1 and 2.

 

I'm using 3 monitor all 2560x1440 on X (horizontal) with 100% resize (no resize)

Main computer control Middle and Left while Secondary computer control Right

My problem is that when I drag my mouse from Main to Secondary the mouse won't reach the correct coordinnates.
Basicly only the 50% lower part of my secondary monitor is recognize as being edging with the main monitor.

Resulting that when I switch on the top corner of the main monitor my mouse enter the secondary screen in the middle.

 

Any possible fix ?

Thanks,

Konorr
