I have just carried out a little experiment....

The LCD display again said no rainfall, yet checking the rainfall graph for the past 24 hours in EW it showed a line which resembled the graph of a severe earthquake - The line was shooting up and down regularly, whereas the line is of the incremental type. Once the total rainfall has been added by additional rainfall the line on the graph should only rise - never ever fall.

If the EasyWether.dat file is deleted, it is replaced the first time you run EW, with data being downloaded from the display back to the time the displays data was last cleared. I deleted the file, then ran EW which downloaded again the data from the display for the past few days from its internal memory of the past few days.

Looking at the same graph for the same period of rainfall in EW (todays rainfall), it is not now showing any false rainfall. This I think proves that the firmware in the LCD display is fine, so the problem must be either in the EW software, or corruption during the tranfer of data via USB. This happened using the EW V4.12. I going to run V1 for a while now.
