FreeNX-related freeze (Windows Client)

view story

http://forums.fedoraforum.org – I'm running a FC19 Hyper-V guest on a Win 8 Pro tablet (Lenovo Helix). Since the Hyper-V viewer limits resolution, I'm using an NX session to connect to the FC19 VM. The problem: When the tablet sleeps, NoMachine's Windows NX Client "freezes" upon awakening the tablet. More specifically, the remote display does not update for input sent (mouse clicks, characters sent, etc.) to the VM, but the VM does receive input sent -- this is evident from killing the Windows NX Client and re-establishing the connection, which produces the expected display output. Question(s): Are there N (HowTos)
