This edit is inside another plugin's file, so a plugin update will undo it. Write the change down, and re-apply it after every update of that plugin — or ask its authors to include the fix on their side, which is the only version that survives. If the change is inside FOX itself, tell us: a fix that has to be re-applied by hand is a bug on our side, not a solution.
