--- Comment #7 from Takenori Yasuda <yassan110...@gmail.com> --- Further observations reveal the following: - New files that contain Validity settings (from Data -> Validity -> Criteria tab -> Allow -> select Cell range) can be saved, but the bug occurs upon exiting. - When editing an existing Validity setting, the application can be closed without triggering the bug. - The bug occurs on exit if a newly created Validity setting is present, regardless of whether the file itself is new or pre-existing. - Even if the creation of the Validity setting is interrupted—for example, by clicking the close button on the Shrink window immediately after pressing the [Shrink] button for the source field—the bug still occurs upon exit. This indicates that completing the cell range selection is not required to trigger this issue. This strongly suggests that the issue specifically arises when a new Validity setting is created with a cell range as its source, even if the creation process is not completed.
