In Calc how do you not rename sheets every time you open one

Hi sorry if this is a numb question but I am new to Libre Office.
on a spredsheet document with more than one sheet and I move between sheets, a box comes up asking do I wish to rename the sheet, it does not seem to mater wether I rename or cancel the box pops up ever time I change sheets.
regards Dave.

I’m guessing that you’re double-clicking to select the tab, which -will- open the Rename Sheet dialog. Just single-click the tab, and that will open the sheet.
