When creating/editing a Tabular note using a large amount of data in
spreadsheet, the updates will take a long time. This is due to the COM
between Excel and NX through shared Windows O/S abilities. After getting the
initial data imported, the spreadsheet edit may no longer be wanted and you
might want to disconnect the Tabular Note from Spreadsheet.
Select the Tabular Note upper left corner where the "+" is, then with MB3 ->
Edit without using Spreadsheet. There will be a warning to acknowledge, and
once done the Tabular Note can be edited as a simple Tabular Note.
