sam60 - One of the things I do when typing a long response is to type it outside of VB (Word Pad, Text Edit [Mac version], MS Word - whatever), and then copy and paste it into the forum. I don't think it's really a VB exclusive issue. These web editors aren't built for tons of word processing.
Hopefully, the jumping around on your screen was a glitch effect from one of the developers working on something. They've been pushing fixes immediately (as I understand) and that can cause funky things to happen sometimes. If it only happens that one time, I'd give it a bit. If it's consistent, grab a screen shot for us. That'll help the developers find it and tighten up the bolts.
As far as a better option for iBoats - I'll let the company speak for themselves. But I will say, they are actively working on stuff. It's currently mostly happening in the store, so the forum is probably a little behind the "fix it" curve. But they are working on it.
