1. Open any excel file
2. filled the worksheet with some data with the first row as the header
3. select all existing data by ctrl +a
4. go to data tab, press sort button
5. tab to any of the dropdown menu
6. press up or down arrow, everytime when I press up or down arrow, nvda will say list box list xxxx
7. after I have selected one of the item and press tab, nvda will repeat the name of the current worksheet and says excel unavailable, followed by the next item.
Would you please comment on whether this is a nvda or excel problem? Thanks.
