This problem occurs when the following two are on.

• 'Save the folder display width'
• 'Restore window state at next startup'

Specifically, the FolderView width must be fixed irrespective of the width of the entire Window, but it actually increases in proportion to the overall width.

Therefore, when restarting, the enlargement is performed twice, and is displayed as a larger width.
