System variable SWFS is added in Origin 2023 to control font in Script window.

If user opens Preferences: System Variables dialog and set the system variable. E.g. set it to 15.

Then close Script window and then close Origin.

When launching Origin.

==> The script window always shows.

Workaround. Delete the swfs in Preferences: System Variables dialog. Instead, set it e.g. @swfs=15 in Script window.
