I've noticed apps disappearing in the Sense/Espresso app drawer, but can't recall if they were stock apps or not.
I'm damn sure that some apps I install from the Market do not show up in the Sense/Espresso app drawer if I install them while in LauncherPro. I can see them in app manager, etc., but they're absent from the app drawer. I have to be in LauncherPro's app drawer in order to see everything I have installed.
Very weird, but this is my 1st HTC device, and I'm running LP as my default. Would still like to know why this is, and if there's anything that can be done to make all apps visible.
