Using Treo 650 with RhinoSkin. I have had a problem with accidental speed-dialing if closing the case while in the phone application. I must be hitting one of the speed-dial buttons unknowingly. Is there a utility that "keyguards" the speed-dial buttons or is there a utility which exits the phone application and returns to ZLauncher or "home" prior to shut-off or after a call? Of course, if I remember to press the "home" button after phone use there is no problem, I but rarely remember to do so. Any suggestions are appreciated!
