qemu-kvm viewer won't type

[ToddAndMargo]

Hi All,

If I do not have any activity in my virtual machine (does
matter what OS) for a bit of time, say 30 minutes, the
mouse works, but I can't type.  Exiting the viewer
and restarting it and happy camping returns.

Is this just a bug or is it just some configuration?

Many thanks,
-T
