[DogParkList] MacLoggerDX cluster activity

[John E Bastin, K8AJS]

I had MLD running on my PowerBook here at the office today, connected 
to a DX cluster keeping an eye on VK9ML (among others).

Does MLD 'ping' the cluster node every once in a while, or something? 
The reason I ask is that at one point in the list I saw 5 'arc >' 
prompts between incoming spots. The only time I normally get a prompt 
is after I've sent a spot to the cluster, or if I just hit an empty 
'return'. I'm not used to seeing all these prompts onscreen; what's 
up?
