@alixdamman did you check this when doing #21? If so, this issue could be closed.

Problem is still there.

This issue can mean two things: updating the window title with * (I think this was the original meaning of the issue) and refreshing the array widget data.

As of version 0.34.3 (and also in the compare_align branch after the "misc cleanups to console handling" commit) I got:

arr = ndtest(5)
arr['a2'] = 10   # detected by array widget but not by title
arr['a2'] *= 10  # detected by neither (but losing focus -- or clicking next 
                 # to the widget -- and regaining it, makes the array widget pick it up)
arr *= 2         # detected by both

I assumed this issue was about the array widget refresh and #280 for window title
