Greetings,

I am a recent user of Mango, still evaluating/ learning about it. I am very interested on providing scada capacity to my Arduino setup, and though being only a mildly capable Arduino user so far Mango seems very fluent and easy to use.

Now, here comes my first difficult problem so far: Since this morning, and (apparently) with no action from my side, Dashboard Designer does not show any graphics whatsoever. I have a very simple system input with 4 variables from Modbus Arduino via USB. Data capture and storage works flawlessly. I very quickly started generating real time gauges from my data points and generating views of them. I have started learning about more complex historic data graphics, but now I can't seem to see graphics any more. I can see and edit code, either in the dashboard designer working space or in the edit pages area, but no graphics at all.. The graphic design area is black and empty, I was able to see again the graphic working area and its elements if I restored a previous revision story, but now that does not seem to work any more.

One more thing, the system is very self-contained, just a laptop connected to an Arduino on my desk, with no networking at all so far (other than internet for the laptop via wifi).

Please tell me, is there anything wrong with my Mango installation? is this some limitation of the evaluation licence?

Thank you for your time and attention.

Javier
