Having said I'd not had it happen, I obviously tempted fate because it happened to me three times over the long weekend!

My remote machine just stoppped responding to keystrokes, my "local" Keyclone didn't show the "remote" WoW sessions any more, and the remote Keyclone had hung. The UI was there, but unresponsive, and I could only get rid of it through task manager.

Now, I have had issues with Keyclone quietly hanging when the machine is totally CPU-bound, so there's some sort of timing problem in there somewhere, but this is the first time I've had it happen on a less-loaded machine.

I wish Keyclone would at least tell me when it's lost a remote connection so I don't get a surprise single character pull

I tried to dump the process, but for reasons I don't fully understand, apparently that's not possible.

I'll try to gather more information about what happens and when for a proper bug report, but there's definitely an issue there.
