Thanks. I can see from your post time that the window for me to complete was too long. I started my post on my iPad, saw something I needed to correct and did it but then I couldn't see the end of the post and no way to scroll down to it. So, that is why I switched to my MBP to complete and why a partial post was on here for several minutes.
If there is a way to scroll in the editing window on the iPad I don't know it.

BTW: I would definitely consider Canon.
