Navigator image not changing while adjustments made in 'Develop Adjustments Panel'

While the main image changes, the 'Navigator Image' does NOT change while adjustments are made in the 'Develop/Adjustments Panel'. It's only when you move the cursor away from the Adjustments Panel and onto the main image, that the 'Navigator Image' changes.

Has anyone had this issue?
