After A HUGE headache with my new 62s, and several not-so-fun caching days of abnormally high blood pressure, I tried this and it seems to have worked. Going from Geocaching dashboard to Geocaching-Detailed dashboard I think has solved the problem. I'll post back if there's still something wrong to let everyone know.
It was so frustrating... I spent weeks researching GPS devices, asking around... spend hundreds of dollars on a brand new device that had so many great reviews, only to have it rendered 95% unusable after upgrading from 2.* to 4.5. Thankfully, changing dashboards seems to have finally got it working again.
Thank you so much, Ron. Cheers from beautiful Autumn in NY!
