6.2 Options Net Change

[finpress2000]

I have two option symbols in a quote sheet:
NQ AU and NQ BU

Strangely, the net change column does not update,
either in the quote sheet or a Single Quote pane.
If you click on the symbol, it updates *once* but then
does not further update as the option prices changes.
A new bug or one that has been there for a while?
