Here's my setup: Primary: Vista Enterprise, in domain (desktop) Secondary: Vista Enterprise, in domain (laptop) Multiplicity Pro 1.21 Switching between machines works and is simple, when they are unlocked. Once the machines are locked, using C+A+B works as C+A+D on the secondary however, Multiplicity (on the primary) pops up the bubble saying connection to secondary lost then says it is connected and I am unable to type in the password box on the secondary. This prevents me from unlocking the secondary without using the laptop keyboard. Any idea on this? I read thru the other posts here and there are some similar issues with unlocking Vista but I didn't see anything explicit to not being able to type.
