Sorry, I got it wrong in my last post. The only combination of extents that works for all options is to have main map extents in lat/long (matching the data) and the reference map extent in the corresponding projection metres.
With this (and only this) combination I can pan on the main map using the pan icons and by clicking the reference mapand, use a rubber band to select a box of interest and have it zoom on the main map and display on the reference map and query points by switching to query mode. Dynamically setting reference map image and extent remains a challenge.
