I use “Freeze Rows & Columns” in nearly every spreadsheet I create. If I need to move or copy a sheet to another location within the same document, the frozen rows & columns are retained. However, when I want to move or copy it to a different Calc document, it loses the frozen formatting. Sure, I just need to redo said freezing, but it’s annoying.
I doubt it matters, but my system is a Toshiba laptop running Windows 8.1 Pro. Whenever I update the LO version, I hope this was fixed; the current version is 7.0.4.
