I'm using Multiplicity 2.0 with primary running Windows 7. I have been experiencing a problem where after I left my computer for a long time (overnight, for example), when I come back, I can't switch machine using mouse button 4 and 5. However, if I scroll the cursor off the screen edge of the primary, then I can control the secondary no problem. Even stranger, once I'm able to control the secondary, mouse button 4 and 5 now work correctly and can switch control between the two computer.
Is this a known issue?
