I'm using the following setup:

Laptop (Windows) - Synergy Server (1.7.4)
Mac Mini (MorphOS) - Synergy Client (MOS 3.9)

Keyboard and mouse work perfectly, but something strange happens when I want to Copy some text in my MOS session. Even when not using a keyboard shortcut, but using the mouse and go to the Edit -> Copy entry in the menu, the pointer activates the laptop session and jumps to the middle of the screen (happens in every program that has a Edit -> Copy menu entry). This also happens when for instance using the keyboard shortcut Ctrl-C.

The server then outputs the following:

ERROR: invalid message from client "MorphOS": DCLP
INFO: jump from "MorphOS" to "Laptop" at...

I also haven't been able to transfer the clipboard content from one machine to the other, but that's something I haven't looked into yet.

Does anyone know what's going on?
