I hope someone can assist with this. I'm running Synergy 1.4.2. I have a Windows 7 machine that is acting as the server, and an Ubuntu 11.04 machine running as client. On the client machine, I cannot use the mouse buttons such as forward and back unless I hold the alt key down. I cannot seem to find any information on why this is, or how to change it. Is this even a Synergy issue?
