Hello,
The Unfreeze Panes in the View always work.. Don't know why it doesn't work over there. In addition, when you click on Unfreeze Pane, it removes the freeze pane from your spreadsheet. If you want to Print columns B,C,D and E for instance, you will need to select all the data in the range you intend to print and then deploy CTRL + P. In the Print Preview, choose selected range and print...
Cheers.
