I have just received a call from esignal.
After some tinkering, one of their support staff has managed to solve the problem it would appear.
The problem apparently was in the applets. The workspace had to be deleted and I must re-build it. No big problem. I hope this solution helps some of the people that PM'd me saying they have had similar issues. The problematic applettes could also have been a reason for data cut-outs.
Thanks to e-signal. Much appreciated.
The promptness of your response has made me look at your company in a much more positive light, and I hope I can continue using your product in the future.
Thanks once again.
