I have OS 6 on my bold, and lately i've noticed that as i'm texting I have been minimizing out of the text, and going to the search midsentence a lot, is there some kind of shortcut I am accidently hitting or something? it's always mid-sentence, but I usually don't mess up too often on texting so I don't think i'm hitting like alt or anything as i text. any suggestions or info about it?
Thanks guys
