dear allin,
there's a strange behaviour of the scalars window (see a screen capture
I run a script which opens a dataset and produces some scalars. Then I open the scalars windows to view the output.
Without closing the scalars windows I re-run the script twice  by changing only the dataset filename to be opened and analyzed.
The scalars window is not refreshed and the new scalars are piled up to the old ones keeping the same names and, some of them showing strange values. Some new and not requested scalars appear for the first time (the 'i's in the picture) while some others supposed to be deleted still appear (the 'essai's in the picture).
