I've jailbroken my iPad 2, and before if I double clicked the home button I could long press on one of the running apps to close it down. Now when I do it, the icons just shake around, but the little x or whatever was there is gone, and i cannot close my apps. I'm sure it is something I've installed, but there are so many things, i don't know where to start. Anyone else run across this? SOLVED: Found the problem. It was iProtect. One of the settings is "Disable App Deletion", which disables the little x when you press and hold on an app. The same setting also disables the little red (-) that pops up when you press and hold in the task switcher.
