Mouse drag bug found

Hi
I just find a bug but don’t know where to report it, so post it here.
Thing is simple, I found no way to drag any game object in scene editor while using Synergy to control my mouse/keyboard.
And everything goes fine if use mouse on computer directly.

Any quick trick? Thanks

Synergy version: 1.4.12, Client mode
Unity : 4.1.5
OS: Mac

Meanwhile, you can drag whatever you want, such as window layout and hierarchy. This only happens in scene editor.
