Hi Thom, I'll tell you what. It was very, very
late, I was very tired, I was pretty frustrated and I did lots and lots of fiddling. It's possible that I didn't uninstall apps while in safe mode, but since I had no idea that I wasn't supposed to until you just told me
it's just as possible that I did. So far the phone seems to be OK so perhaps I got lucky!
I also emailed the developer a few minutes ago to report the bug. I liked the app so I hope he will fix it.
