I get this problem when I'm typing a post some times and also when typing an e mail. If I go back to try to change some thing, such as spelling or some such dodgy grammar, I get this blue upright blob, instead of the usual narrow black vertical line. Trouble is that it kind of keeps deleting what is in front of it, as I alter my text. It's pretty annoying, so sometimes I just give up and write it all again. With one finger that aint easy. Any ideas how I stop this blue vertical blob? It's really getting to me at times, and makes me want to give up, which I have done on more than one occasion.
