Hi Lucas, after sever trials now I am successfully running my observatory based on TSX+ACP+Maxdome. Just follow the other suggestions here (have TSX not sleeping in minimize) and make sure to have their latest build installed. I had some pointing issues at a certain point but turned out to be a problem of wrong sync data stored in TSX, you need to see the instructions on how to clean them in their Paramount ME-II manual.
Touching wood now all is working in my set up (or at least quite ok, still other issues to fix but apparently related to my hardware).
I agree with you that there is no real point in upgrading unless you have to, like in my case where I am running all on a Win7-64 bit system and was unable to get thesky6 and paramount woring with that configuration..
Regards
Marco
