@Sonphil - Since you say you don't speak English very well, I'll explain what tueidj is trying to say. You misspelled "stuttering" for "sluttering" (note the "T" instead of an "L"). "Sluttering" isn't a real word (not yet?) but it contains a negatively associated root word. In short, it's an awkward spelling error 
But this is all off-topic now, especially since you fixed your issue. Anyway, enjoy Dolphin now that things are working.
