I upgraded to 2.85 yesterday and used my Oregon for some caching today.
One thing I noticed is that the Pointer and Dist to Dest displays on the map screen seem to be less responsive. When I am navigating within close range of a cache, these displays seem to hang and don't update like they used to.
I really liked using the Oregon in this way, I hardly ever went to the compass screen to zero in on the cache, the display on the map screen was accurate enough for me to usually make the grab.
It is somewhat strange, because when I am traveling quickly in the car it seems to do fine but when I set out on foot it tends to begin updating slowly and then hangs and will not update at all. If I cancel out of the map and go back to it, it displays accurately but doesn't update when I begin moving again.
Has anyone else noticed this or do I have other problems than the update? I'm might try to downgrade to see if this resolves.
