Simlink xplane unexpected behaviour

Charts Simlink/Moving Map
1

Xplane (11 or 12) is openning “file explorer” xplane folder, when loading.
If I delete NavigraphSimlink_64.xpl the problem disappears.
How to correct this behaviour without deleting this file ?

If using Firefox, please see FAQ - Firefox may start an app when Simlink Starts .
