Temp scale on main window in error 9.81a

The temperature scale on the graph in the main display is in error, the graph indicates a current temp of 82 while the actual temp is 91, if I click on the graph to get the detailed graph, the scale and graph show the correct temp.

ok, when this happens, email me your latest.inf file from the folder datafiles
and your wdisplay.ini file from c:\windows or c:\winnt
