I've been using Synergy (& various of it's incarnations) on a multitude of platforms for server years now, but something weird seems to be occurring.
QuickSynergy stopped working on Mac OS/X (10.6), either as client or server, so I've removed it & loaded on QSynergy using it as a server to my Linux/Ubuntu (CLI) synergyc slave/client.
Connection seems OK & mouse cursor crosses screens/desktop, but keyboard events/key-presses aren't working. When pressing keys on keyboard while mouse cursor's on non-primary/client screen, it's being registered on the server.
