I notice that when I sort the portfolios, the chart display doesn't change.
I hope I can explain clearly.
If I display a portfolio then select a line within the portfolio, the chart changes.
But then sort on a different column, the chart doesn't change and the highlight bar doesn't de-select in it's line position, and you can't display the chart on whatever the new line item is under the selection, until you select a different line then go back.
It looks like the highlight needs to follow the item when re-sorting instead of staying stationary on the re-sort.
To me it's not a terrible thing since the work around is to select another item then go back.
