Can't delete worksheets
When I try to delete pages from my workbooks, two boxes appears at the bottom of the screen which ask if I'm sure I want to delete the page or cancel. I can't click on Yes, delete it because it is covered partially by an ad. How can I delete pages without this?

Hello,
I understand your point, it could be the browser's zoom, you can adjust it to see if the covered part is now visible. Please refer to the image attached.
I hope this points you in the right direction. Let us know how that goes :)
