Changed a widget on the dashboard but the refresh breaks it

[mrhub]

Hello!
I have added the temperatures according to the http://dbknickerbocker.blogspot.se/2013/03/adding-cpu-temperature-monitoring-to.html and it works for about 10 sec, then the first temp says "Array°C", not the temperature. (see the attachments)
My guess is that the refresh uses another function to get the temperature.

Does someone know where to update the function so it works more than 10 sec?
