I use Handcent for my messaging and hate the stock app. When I'm getting an incoming text message when the phone is just in idle mode, I get that pop up with the text message in it from the stock messaging application. I went into the settings of that app and attempted to stop it from happening. I also attempted to disable it from Handcent. But, I'm still get the pop up and have to "x" out of it. Does anyone even understand my dilemma?
