I'm running Multiplicity 2.01 build 00030 - Windows 8 64 master Windows 7 64 slave.

I'm having difficulty with the Scroll Lock toggle feature under "Mouse Switching".

If I enable this feature, then mouse over to the slave, lock the slave, the mouse pointer won't move back until I press scroll lock ON (?!)

After that I'll sometimes need it on, sometimes off, to transition the mouse. Eventually Multiplicity gets so confused my keyboard and mouse stops responding altogether.

Bit more info, I think this might be caused by the "Prevent computer switching via mouse movements: When a fullscreen application is running" option. Multiplicity seems to treat the lock screen as a full screen application on the slave, preventing you from switching the mouse back after locking it.
