--- Comment #8 from George Tzan <g.tza...@gmail.com> --- As per your request "Options - LibreOffice - View - Use Skia for all rendering" deactivated. No difference at all. Problem is there. The problem can be reproduced in Safe Mode. You have to follow the process described in my last comment and repeated below: ======================================================================== Load in Safe Mode. Edit->Cell Protection is OK. Indicates with a tick, the current cell protection attribute. Customize Edit menu. Remove and then Add again Cell Protection item. Edit->Cell Protection is a fix lock and does not indicate the current cell protection ======================================================================== -- You are receiving this mail because: You are the assignee for the bug.
