If you tick the connect on startup box in os link options (next to run as a service box) then it will connect without user intervention.

can't say ive tried dataview in firefox, but given samsung's track record with web interfaces (web mmc) and firefox not working, id say it won't.

If you have 4.30 or later on a OS7000 you can enable the tutorial license which will give you 2 x softphone licenses to play with for 14 days.

Make sure you get the latest version of dataview (esp is your server is 64bit)
