NIS 18.1 did not have this...
But now NIS 18.5 german edition has same bug as N360 v5 beta!
In Norton Tasks the "Process" info box appears if you click on an item on the chart.
Move the mouse - "Process" info box stays as long as the mouse curser remains "inside the graph area".
Click beside the "Process" info box on the chart again - the first info box disappears, 2nd "Process" info box comes up.
Move the mouse "inside the graph area" - "Process" info box disappears.
Reproduced on virtual machine german XP 32 Bit SP3, IE8
