I can try turning off the Windows Firewall, sure, but I'm surprised because this issue came "all of a sudden". I think it's with version 2.5.1.17 though. I will revert back to 2.5.1.15 and try that because I have never had this issue before.
Andy read this thread (on my e-mail request) and he believes this is an issue with SGP completing the plate solving exposure download. Now, I do know SGP is working with my camera perfectly in that all actual imaging exposures are downloaded perfectly well, but I also think Ansvr is working well as when "nothing happens", it's actually sitting there "Waiting for data" so supposedly Ansvr is doing its job, just that SGP is not handing over the task of plate solving.
I will try this all again with SGP 2.5.1.15 and will report back. If the problem persists, I will post a log file.
