I knew this would happen. I might have to take one of my discoveries back
I played with using the shutter button for focus again. Combined with continuous focus mode.
One thing I noticed. It made getting pictures of birds in flight a little less complicated. I had a flock of Pacific Black Ducks giving me a grand old show this morning and managed some acceptable shots this way.
I may stick with shutter button focus for a bit and see - I’m wondering if it will help with some of my focusing issues (maybe pushing the back button is pushing me off target?)
