Upgrade good! Just to let folks know--I upgraded this app outside the market. The payment was through Paypal, so I trusted it. The process was more complicated than through Google Market, and I had to email developer to figure things out, but they responded quickly and the app downloaded without incident. I believe the dev is sincere and honest(the product is GREAT), but they would sell a lot more if they went through Google.. .don't know why they don't.
